How to Find the Factors of 157?

To find the factors of 157, we will have to find the list of numbers that would divide 157 without leaving any remainder.

• 157/157 = 1; therefore, 157 is a factor of 157.
• 157/1 = 157; therefore, 1 is a factor of 157.

Hence, the factors of 157 are 1, 157.

• Factors of 13 - The factors of 13 are 1, 13
• Factors of 32 - The factors of 32 are 1, 2, 4, 8, 16, 32
• Factors of 44 - The factors of 44 are 1, 2, 4, 11, 22, 44
• Factors of 8 - The factors of 8 are 1, 2, 4, 8
• Factors of 15 - The factors of 15 are 1, 3, 5, 15

The number 157 is prime and therefore its factors are only the numbers 1 and 157 itself. Hence, it has only one prime factor that is the number itself, i.e. 157.

So, the prime factorization of 157 can be written as 157¹ where 157 is prime.

Pair factors of 157 are the pairs of numbers that when multiplied give the product 157. The factors of 157 in pairs are:

• 1 × 157 = (1, 157)

Negative pair factors of 157 are:

• -1 × -157 = (-1, -157)

NOTE: If (a, b) is a pair factor of a number then (b, a) is also a pair factor of that number.
