The primes you divided by give 904 = 2³ × 113. From the exponents you can also count the factors without listing them: (3 + 1) × (1 + 1) = 8.

Properties of 904

• 904 is a composite number.
• The sum of all its factors is 1,710; the sum of its proper factors (excluding 904) is 806, which makes it a deficient number (its proper factors add up to less than itself).
• 904 is not a perfect square, so its factors pair up evenly.
• Multiples of 904 include 1,808, 2,712, 3,616, 4,520 and so on.
