Factors of 102

How to find the factors of 102

Test every whole number from 1 up to the square root of 102 (√102 ≈ 10.100). Each number that divides evenly gives you two factors at once: the divisor and the quotient.

• 102 ÷ 1 = 102 — so 1 and 102 are factors
• 102 ÷ 2 = 51 — so 2 and 51 are factors
• 102 ÷ 3 = 34 — so 3 and 34 are factors
• 102 ÷ 4 = 25.5 — not a whole number
• 102 ÷ 5 = 20.4 — not a whole number
• 102 ÷ 6 = 17 — so 6 and 17 are factors
• 102 ÷ 7 = 14.571 — not a whole number
• 102 ÷ 8 = 12.75 — not a whole number
• 102 ÷ 9 = 11.333 — not a whole number
• 102 ÷ 10 = 10.2 — not a whole number

Collecting both numbers from every successful division gives the complete list: 1, 2, 3, 6, 17, 34, 51 and 102.

Prime factorization of 102

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

The primes you divided by give 102 = 2 × 3 × 17. From the exponents you can also count the factors without listing them: (1 + 1) × (1 + 1) × (1 + 1) = 8.

Properties of 102

• 102 is a composite number.
• The sum of all its factors is 216; the sum of its proper factors (excluding 102) is 114, which makes it a abundant number (its proper factors add up to more than itself).
• 102 is not a perfect square, so its factors pair up evenly.
• Multiples of 102 include 204, 306, 408, 510 and so on.

Factors vs. multiples

Factors of 102 are the numbers that divide into it; multiples of 102 are the numbers it divides into. Every number has a limited set of factors but infinitely many multiples. To work with any other number, use the factors calculator, or find shared factors with the GCF calculator.
