Factors of 857 by Prime Factorization

The number 857 is prime and therefore its factors are only the numbers 1 and 857 itself. Hence, it has only one prime factor that is the number itself, i.e. 857.

So, the prime factorization of 857 can be written as 857¹ where 857 is prime.

Factors of 857 in Pairs

Pair factors of 857 are the pairs of numbers that when multiplied give the product 857. The factors of 857 in pairs are:

1 × 857 = (1, 857)

Negative pair factors of 857 are:

-1 × -857 = (-1, -857)

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

Factors of 857 Solved Examples

Example 1: How many factors are there for 857?

Solution:

The factors of 857 are 1, 857. Therefore, 857 has 2 factors.
Example 2: Find the Lowest Common Multiple (LCM) and Greatest Common Divisor (GCD) of 857 and 65.

Solution:

The factors of 857 are 1, 857 and factors of 65 are 1, 5, 13, 65.

Therefore, the Lowest Common Multiple (LCM) of 857 and 65 is 55705 and Greatest Common Divisor (GCD) of 857 and 65 is 1.
Example 3: Find if 493 and 857 are factors of 857.
