What makes 242 interesting

  • 242 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.
  • 242 is a deficient number: its proper factors sum to 157, which is 85 less than 242 itself.

How to find the factors of 242 yourself

Divide 242 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 √24215.56, because every factor above that pairs with one below it.

242 ÷ 1 = 242
242 ÷ 2 = 121
242 ÷ 11 = 22

Reading both columns gives every factor: 1, 2, 11, 22, 121, 242. The factor calculator does this automatically for any number.
