## What are the prime factors of 72?

So, the prime factorisation of 72 are 2 × 2 × 2 × 3 × 3 or 23 × 32, where 2 and 3 are the prime numbers..

## What is the greatest prime factor of 24?

Answer and Explanation: The prime factorization of the number 24 is 2 × 2 × 2 × 3. You can also write this with exponents as 23 × 3.

## What is a prime common factor?

A common factor of two numbers is a factor that divides both numbers. The greatest common factor (GCF) of two numbers is the greatest number that divides both numbers. To find the GCF, take the prime factorization of both numbers. … For example, the greatest common factor of 1,575 and 23,100 is 3×5×5×7 = 525.

## How do you find the greatest prime factor?

To find the greatest common factor (GCF) between numbers, take each number and write its prime factorization. Then, identify the factors common to each number and multiply those common factors together.

## What is the prime factorisation of 200?

The prime factorization of 200 is as follows: 200 = 2 × 2 × 2 × 5 × 5.

## What is the largest perfect square factor of 200?

Answer : 1,2,4,5,8,10,20,25,40,50,100,200, Related Links : Is 200 a rational number?

## What is the prime factor of 81?

81 and Level 5 81 is a composite number and is 9 squared. 81 = 1 x 81, 3 x 27, or 9 x 9. Factors of 81: 1, 3, 9, 27, 81. Prime factorization: 81 = 3 x 3 x 3 x 3 which can also be written 3⁴.

## What is 12 as a product of primes?

For example, 5 is a prime number, because the only factors of 5 are 1 * 5 = 5. However, 12 is not a prime number, because 1 * 12 = 12, 2 * 6 = 12, and 3 * 4 = 12. Prime factorization means finding all the prime numbers that are factors of a number. 2 If the last digit is even, the number is divisible by 2.

## What is the greatest prime factor of 77?

77 is a composite number. 77 = 1 x 77 or 7 x 11. Factors of 77: 1, 7, 11, 77. Prime factorization: 77 = 7 x 11.

## What is the GCF of 12 and 30?

Earlier we found that the Common Factors of 12 and 30 are 1, 2, 3 and 6, and so the Greatest Common Factor is 6. The Greatest Common Factor of 12 and 30 is 6.

## What are the perfect square from 1 to 100?

The perfect squares are the squares of the whole numbers: 1, 4, 9, 16, 25, 36, 49, 64, 81, 100 …

## What is the largest prime factor of 200?

Positive Integer factors of 200 = 2, 4, 8, 5, 40, 200 divided by 2, 2, 2, 5, 5, gives no remainder. They are integers and prime numbers of 200, they are also called composite number.

## What is the factors of 200?

Factors of 200 are 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100.

## What is the GCF of 4 and 10 using prime Factorizations?

Greatest common factor (GCF) of 4 and 10 is 2. We will now calculate the prime factors of 4 and 10, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 4 and 10.

## IS 400 a perfect square?

A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 400 is 20. Therefore, the square root of 400 is an integer, and as a consequence 400 is a perfect square.

## IS 200 a perfect square?

A perfect square is the number which is exactly equal to multiplication of 2 equal integers twice. … As 200 cannot exactly meet the above criteria, it is neither a perfect cube nor a perfect square. 200=14.1421*14.1421. As 14.1421 is not a integer 200 is not a perfect square.

## What is the greatest common prime factor?

The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4.

## What is the greatest prime factor of 100?

The factors of 100 are: 1 × 100, 2 × 50, 4 × 24, 5 × 20, 10 ×10. The greatest prime factor of 100 is 5 = n.
