## How do you find the factors of 28?

28 = 1 x 28, 2 x 14, or 4 x 7. Factors of 28: 1, 2, 4, 7, 14, 28. Prime factorization: 28 = 2 x 2 x 7, which can also be written 28 = 2² x 7. When 28 is a clue in the FIND THE FACTORS puzzles, the factors will be 4 and 7.

## Is 28 a perfect number?

28 is perfect too: 14, 7, 4, 2, and 1 add up to 28. But perfect numbers aren’t common at all. There are only two more, 496 and 8,128, below a million. Only 50 total perfect numbers are known, even with a dedicated worldwide effort to computationally discover more.

## What are the common factors of 36?

1, 2, 3, 4, 6, 9, 12, 18, and 36. 1, 2, 3, 6, 9, 18, 27, and 54. Although the numbers in bold are all common factors of both 36 and 54, 18 is the greatest common factor.

## Is 35 a perfect square?

Is 35 a perfect square number? 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 35 is about 5.916. Thus, the square root of 35 is not an integer, and therefore 35 is not a square number.
