The factors of 60 are the whole numbers that divide 60 exactly, leaving no remainder: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60. Use the calculator above for any number, or read on for the factor pairs, prime factorization and properties of 60.
What are the factors of 60?
A factor of 60 is any whole number that divides 60 with no remainder. Listing them from smallest to largest, the factors of 60 are:
1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
So 60 is a composite number with 12 factors in total. Every number has 1 and itself as factors; the interesting work is finding the ones in between.
Factor pairs of 60
A factor pair is two numbers that multiply to give 60. The factor pairs of 60 are:
| Factor pair | Product |
|---|---|
| 1 × 60 | 60 |
| 2 × 30 | 60 |
| 3 × 20 | 60 |
| 4 × 15 | 60 |
| 5 × 12 | 60 |
| 6 × 10 | 60 |
Prime factorization of 60
The prime factorization breaks 60 down into a product of prime numbers only:
$$ 60 = 2^{2} \times 3 \times 5 $$How to find the factors of 60, step by step
- Start at 1 — 1 divides every number, so 1 and 60 are always factors.
- Test each whole number from 2 upward: if it divides 60 exactly, it is a factor.
- Use factor pairs — each small factor gives a matching large factor, so you only need to test up to $\sqrt{60}$.
- List them in order to get all 12 factors of 60.
Factors versus multiples of 60
It is easy to mix these up. The factors of 60 are the numbers that divide into 60 (they are less than or equal to 60), while the multiples of 60 are what you get by multiplying 60 outward: 60, 120, 180, 240, and so on. In short: factors go in, multiples go out. 60 is an even number, and its smallest prime factor is 2.
Properties of 60
| Number of factors | 12 |
| Sum of factors | 168 |
| Sum of proper divisors | 108 |
| Prime or composite | Composite |
| Even or odd | Even |
| Perfect square | No |
| Prime factorization | 2^2 x 3 x 5 |
Is 60 abundant, deficient or perfect?
Number theorists classify a number by comparing it to the sum of its proper divisors (all its factors except itself). For 60, those proper divisors add up to 108, which makes 60 an abundant number (its proper divisors sum to 108, which is more than 60). Most numbers are deficient; abundant and perfect numbers are comparatively rare, which is what makes this property interesting.
Using the factors of 60 for GCF and LCM
The prime factorization $2^{2} \times 3 \times 5$ is the shortcut for combining 60 with another number. To find the greatest common factor (GCF), take the primes 60 shares with the other number, each to the lowest power. For the least common multiple (LCM), take every prime that appears in either number, each to the highest power. This is why the prime factorization is worth writing down — it does the heavy lifting for fractions, ratios and simplification.
