Factors of 228

How to find the factors of 228

Test every whole number from 1 up to the square root of 228 (√228 ≈ 15.100). Each number that divides evenly gives you two factors at once: the divisor and the quotient.

• 228 ÷ 1 = 228 — so 1 and 228 are factors
• 228 ÷ 2 = 114 — so 2 and 114 are factors
• 228 ÷ 3 = 76 — so 3 and 76 are factors
• 228 ÷ 4 = 57 — so 4 and 57 are factors
• 228 ÷ 5 = 45.6 — not a whole number
• 228 ÷ 6 = 38 — so 6 and 38 are factors
• 228 ÷ 7 = 32.571 — not a whole number
• 228 ÷ 8 = 28.5 — not a whole number
• 228 ÷ 9 = 25.333 — not a whole number
• 228 ÷ 10 = 22.8 — not a whole number
• 228 ÷ 11 = 20.727 — not a whole number
• 228 ÷ 12 = 19 — so 12 and 19 are factors
• 228 ÷ 13 = 17.538 — not a whole number
• 228 ÷ 14 = 16.286 — not a whole number
• 228 ÷ 15 = 15.2 — not a whole number

Collecting both numbers from every successful division gives the complete list: 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114 and 228.

Prime factorization of 228

Divide by the smallest prime that fits, and keep going until the quotient is 1:

The primes you divided by give 228 = 2² × 3 × 19. From the exponents you can also count the factors without listing them: (2 + 1) × (1 + 1) × (1 + 1) = 12.

Properties of 228

• 228 is a composite number.
• The sum of all its factors is 560; the sum of its proper factors (excluding 228) is 332, which makes it a abundant number (its proper factors add up to more than itself).
• 228 is not a perfect square, so its factors pair up evenly.
• Multiples of 228 include 456, 684, 912, 1,140 and so on.
