## What are two factors of 17?

The two numbers which get multiplied and produce the result as 17, then these numbers are the factors of 17.

Since 17 is a prime number, therefore it has only two factors, i.e.

1 and 17..

## Is 25 prime or composite?

Explanation: 25 has more factors than just 1 and 25 making it composite. The list of factors that it has is 1, 5, and 25. A composite number is a product of prime numbers.

## Is 17 prime or composite?

When a number has more than two factors it is called a composite number. Here are the first few prime numbers: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, 199, etc.

## Is 32 a composite number?

If the factors of 32 are only 32 and 1, then we know that 32 is a prime number. Otherwise, 32 is a composite number. To explain better, if 32 is only divisible by 1 and 32, then it is a prime number, and if 32 is divisible by more than 32 and 1, then it is a composite number.

## Is 42 a composite number?

To determine if 42 is a prime number or a composite number, we simply look at the factors for 42. If the factors of 42 are only 42 and 1, then we know that 42 is a prime number. Otherwise, 42 is a composite number.

## What is Coprime number?

In number theory, two integers a and b are said to be relatively prime, mutually prime, or coprime (also written co-prime) if the only positive integer (factor) that divides both of them is 1. … A set of integers can also be called coprime if its elements share no common positive factor except 1.

## Which is the smallest prime number?

The smallest prime numbers are 2, 3, 5, 7, 11, 13, 17, 19 and 23. The number 2 is the only even prime number. The number 7 has only two factors: 1 and itself. The number 11 has only two factors: 1 and itself.

## What is composite number and prime number?

Example: 7 When a number can be divided up exactly it is a Composite Number. When a number cannot be divided up exactly it is a Prime Number.

## What is the greatest composite number between 1 and 10?

What are Composite Numbers from 1 to 100?Composite numbers between 1 to 104, 6, 8, 9, 10Composite numbers between 51 to 10051, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 1004 more rows

## Why is 11 not a prime number?

For 11, the answer is: yes, 11 is a prime number because it has only two distinct divisors: 1 and itself (11). As a consequence, 11 is only a multiple of 1 and 11.

## Is 22 a composite number?

A composite number is a number greater than 1 that can be created by multiplying two smaller, natural numbers. Because 22 can be formed by multiplying two smaller, natural numbers, it is composite. 22 is composite because it has four factors.

## Is 17 divisible by any number?

The smallest multiples of 17 are: 0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 17 too, since 0 × 17 = 0. 17: indeed, 17 is a multiple of itself, since 17 is evenly divisible by 17 (we have 17 / 17 = 1, so the remainder of this division is indeed zero)

## Which is the smallest composite number?

41 is neither a prime number nor a compostie number. All even number except 2 are composite numbers. 4 is the smallest composite number.

## What number is a composite number?

The first few composite numbers (sometimes called “composites” for short) are 4, 6, 8, 9, 10, 12, 14, 15, 16, … (OEIS A002808), whose prime decompositions are summarized in the following table. Note that the number 1 is a special case which is considered to be neither composite nor prime.

## Are all composite numbers divisible by 2 or 3?

One proof: Because 2 is a divisor of every even number, every even number larger than 2 has at least three distinct positive divisors. … So, because all the other even numbers are divisible by themselves, by 1, and by 2, they are all composite (just as all the positive multiples of 3, except 3, itself, are composite).

## Is 51 prime or composite?

No, 51 is NOT a prime number because it has more than two factors. 51 is a composite number and can be factored by any of the following numbers: 1, 3, 17, 51.

## Is 21 a composite?

A composite number is a number that can be divided evenly by more numbers than 1 and itself. It is the opposite of a prime number. The number 21 can be evenly divided by 1, 3, 7 and 21, with no remainder. Since 21 cannot be divided by just 1 and 21, it is a composite number.

## What are the composite numbers from 1 to 100?

4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100.

## Is 37 a composite number?

A prime number is a whole number that only has two factors which are itself and one. … Therefore all numbers that end with five and are greater than five are composite numbers. The prime numbers between 2 and 100 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89 and 97.
