What makes 804 interesting

  • 804 is a composite number, meaning it has more than two factors. It can be written as a product of smaller whole numbers in 6 different ways.
  • 804 is an abundant number: its proper factors sum to 1100, which is 296 more than 804 itself.
  • 804 has 3 distinct prime factors (2, 3, 67), which is why it has so many divisors.

How to find the factors of 804 yourself

Divide 804 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 √80428.35, because every factor above that pairs with one below it.

804 ÷ 1 = 804
804 ÷ 2 = 402
804 ÷ 3 = 268
804 ÷ 4 = 201
804 ÷ 6 = 134
804 ÷ 12 = 67

Reading both columns gives every factor: 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804. The factor calculator does this automatically for any number.
