What makes 272 interesting

  • 272 is a composite number, meaning it has more than two factors. It can be written as a product of smaller whole numbers in 5 different ways.
  • 272 is an abundant number: its proper factors sum to 286, which is 14 more than 272 itself.

How to find the factors of 272 yourself

Divide 272 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 √27216.49, because every factor above that pairs with one below it.

272 ÷ 1 = 272
272 ÷ 2 = 136
272 ÷ 4 = 68
272 ÷ 8 = 34
272 ÷ 16 = 17

Reading both columns gives every factor: 1, 2, 4, 8, 16, 17, 34, 68, 136, 272. The factor calculator does this automatically for any number.
