What makes 508 interesting

  • 508 is a composite number, meaning it has more than two factors. It can be written as a product of smaller whole numbers in 3 different ways.
  • 508 is a deficient number: its proper factors sum to 388, which is 120 less than 508 itself.

How to find the factors of 508 yourself

Divide 508 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 √50822.54, because every factor above that pairs with one below it.

508 ÷ 1 = 508
508 ÷ 2 = 254
508 ÷ 4 = 127

Reading both columns gives every factor: 1, 2, 4, 127, 254, 508. The factor calculator does this automatically for any number.
