Factors of 122

How to find the factors of 122

Test every whole number from 1 up to the square root of 122 (√122 ≈ 11.045). Each number that divides evenly gives you two factors at once: the divisor and the quotient.

• 122 ÷ 1 = 122 — so 1 and 122 are factors
• 122 ÷ 2 = 61 — so 2 and 61 are factors
• 122 ÷ 3 = 40.667 — not a whole number
• 122 ÷ 4 = 30.5 — not a whole number
• 122 ÷ 5 = 24.4 — not a whole number
• 122 ÷ 6 = 20.333 — not a whole number
• 122 ÷ 7 = 17.429 — not a whole number
• 122 ÷ 8 = 15.25 — not a whole number
• 122 ÷ 9 = 13.556 — not a whole number
• 122 ÷ 10 = 12.2 — not a whole number
• 122 ÷ 11 = 11.091 — not a whole number

Collecting both numbers from every successful division gives the complete list: 1, 2, 61 and 122.

Prime factorization of 122

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

The primes you divided by give 122 = 2 × 61. From the exponents you can also count the factors without listing them: (1 + 1) × (1 + 1) = 4.

Properties of 122

• 122 is a composite number.
• The sum of all its factors is 186; the sum of its proper factors (excluding 122) is 64, which makes it a deficient number (its proper factors add up to less than itself).
• 122 is not a perfect square, so its factors pair up evenly.
• Multiples of 122 include 244, 366, 488, 610 and so on.

Factors vs. multiples

Factors of 122 are the numbers that divide into it; multiples of 122 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.
