What makes 102 interesting

  • 102 is a composite number, meaning it has more than two factors. It can be written as a product of smaller whole numbers in 4 different ways.
  • 102 is an abundant number: its proper factors sum to 114, which is 12 more than 102 itself.
  • 102 has 3 distinct prime factors (2, 3, 17), which is why it has so many divisors.

How to find the factors of 102 yourself

Divide 102 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 √10210.10, because every factor above that pairs with one below it.

102 ÷ 1 = 102
102 ÷ 2 = 51
102 ÷ 3 = 34
102 ÷ 6 = 17

Reading both columns gives every factor: 1, 2, 3, 6, 17, 34, 51, 102. The factor calculator does this automatically for any number.
