How to find the factors of 34
Test every whole number from 1 up to the square root of 34 (√34 ≈ 5.831). Each number that divides evenly gives you two factors at once: the divisor and the quotient.
- 34 ÷ 1 = 34 — so 1 and 34 are factors
- 34 ÷ 2 = 17 — so 2 and 17 are factors
- 34 ÷ 3 = 11.333 — not a whole number
- 34 ÷ 4 = 8.5 — not a whole number
- 34 ÷ 5 = 6.8 — not a whole number
Collecting both numbers from every successful division gives the complete list: 1, 2, 17 and 34.
Prime factorization of 34
Divide by the smallest prime that fits, and keep going until the quotient is 1:
The primes you divided by give 34 = 2 × 17. From the exponents you can also count the factors without listing them: (1 + 1) × (1 + 1) = 4.
Properties of 34
- 34 is a composite number.
- The sum of all its factors is 54; the sum of its proper factors (excluding 34) is 20, which makes it a deficient number (its proper factors add up to less than itself).
- 34 is not a perfect square, so its factors pair up evenly.
- Multiples of 34 include 68, 102, 136, 170 and so on.
Factors vs. multiples
Factors of 34 are the numbers that divide into it; multiples of 34 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.
