How to Find the Factors of 531?

To find the factors of 531, we will have to find the list of numbers that would divide 531 without leaving any remainder.

• 531/177 = 3; therefore, 177 is a factor of 531 and 3 is also a factor of 531.
• 531/59 = 9; therefore, 59 is a factor of 531 and 9 is also a factor of 531.

Similarly we can find other factors. Hence, the factors of 531 are 1, 3, 9, 59, 177, 531.

• Factors of 56 - The factors of 56 are 1, 2, 4, 7, 8, 14, 28, 56

The number 531 is composite and therefore it will have prime factors. Now let us learn how to calculate the prime factors of 531. The first step is to divide the number 531 with the smallest prime factor, here it is 3. We keep dividing until it gives a non-zero remainder.

• 531 ÷ 3 = 177
• 177 ÷ 3 = 59

Further dividing 59 by 3 gives a non-zero remainder. So we stop the process and continue dividing the number 59 by the next smallest prime factor. We stop ultimately if the next prime factor doesn't exist or when we can't divide any further.

So, the prime factorization of 531 can be written as 3² × 59¹ where 3, 59 are prime.

Pair factors of 531 are the pairs of numbers that when multiplied give the product 531. The factors of 531 in pairs are:

• 1 × 531 = (1, 531)
• 3 × 177 = (3, 177)
• 9 × 59 = (9, 59)

Negative pair factors of 531 are:

• -1 × -531 = (-1, -531)
• -3 × -177 = (-3, -177)
• -9 × -59 = (-9, -59)

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