What makes 252 interesting

  • 252 is a composite number, meaning it has more than two factors. It can be written as a product of smaller whole numbers in 9 different ways.
  • 252 is an abundant number: its proper factors sum to 476, which is 224 more than 252 itself.
  • 252 has 3 distinct prime factors (2, 3, 7), which is why it has so many divisors.

How to find the factors of 252 yourself

Divide 252 by each whole number starting from 1. Whenever the division leaves no remainder, both the divisor and the quotient are factors. You only need to test up to √25215.87, because every factor above that pairs with one below it.

252 ÷ 1 = 252
252 ÷ 2 = 126
252 ÷ 3 = 84
252 ÷ 4 = 63
252 ÷ 6 = 42
252 ÷ 7 = 36
252 ÷ 9 = 28
252 ÷ 12 = 21
252 ÷ 14 = 18

Reading both columns gives every factor: 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252. The factor calculator does this automatically for any number.
