Factors are the numbers that are multiplied together to get another number. To find the factors of a given number, the number is divided by other numbers smaller than the given number, as the factor of any number cannot ...

The number with the most factors is infinite. The number with the most known factors contains all of the prime numbers, of which Euclid's theorem also suggests there is an infinite number.

The positive number factors of the number 63 are: 1, 3, 7, 9, 21, and 63. The easiest way to find the factors of a number is through a series of equations that use basic division.


The factors of the number 23 are 23 and 1. Factors of a number are the numbers that are multiplied together to equal the given number.

Prime numbers that, when multiplied, equal another number are said to be the “prime factors” of that number. For example, 2 and 7 are the prime factors of the number 14.

To find the greatest common factor of two or more numbers, find the factors of each number, then circle the shared factors. Choose the greatest factor that the numbers share.

The prime factorization of 35 is 5 and 7. Prime factors are numbers that are only divisible by themselves and one. While every number is divisible by one, most mathematicians do not consider it as a prime factor.
