How to Find the Factors of 521?

To find the factors of 521, we will have to find the list of numbers that would divide 521 without leaving any remainder.

• 521/521 = 1; therefore, 521 is a factor of 521.
• 521/1 = 521; therefore, 1 is a factor of 521.

Hence, the factors of 521 are 1, 521.

• Factors of 34 - The factors of 34 are 1, 2, 17, 34
• Factors of 180 - The factors of 180 are 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
• Factors of 27 - The factors of 27 are 1, 3, 9, 27
• Factors of 13 - The factors of 13 are 1, 13

The number 521 is prime and therefore its factors are only the numbers 1 and 521 itself. Hence, it has only one prime factor that is the number itself, i.e. 521.

So, the prime factorization of 521 can be written as 521¹ where 521 is prime.

Pair factors of 521 are the pairs of numbers that when multiplied give the product 521. The factors of 521 in pairs are:

• 1 × 521 = (1, 521)

Negative pair factors of 521 are:

• -1 × -521 = (-1, -521)

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