What makes 502 interesting

  • 502 is a composite number, meaning it has more than two factors. It can be written as a product of smaller whole numbers in 2 different ways.
  • 502 is a deficient number: its proper factors sum to 254, which is 248 less than 502 itself.

How to find the factors of 502 yourself

Divide 502 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 √50222.41, because every factor above that pairs with one below it.

502 ÷ 1 = 502
502 ÷ 2 = 251

Reading both columns gives every factor: 1, 2, 251, 502. The factor calculator does this automatically for any number.
