Factors of 3
The factors of 3 are the numbers that divide it exactly. Finding factors is the first step in simplifying fractions and factoring expressions.
A prime page: the factor list holds exactly two entries — 1 and 3 — with nothing living between them. The pairing column shows the only split that exists, 1 × 3 = 3. The largest prime factor is 3 itself, and every factor together sums to 4. Two different primes share no factor except 1, which is why the GCF of two primes is always 1 — and why a fraction whose top and bottom are both prime cannot be simplified at all.
| Factor | Pairing |
|---|---|
| 1 | 1 × 3 = 3 |
| 3 | 3 × 1 = 3 |
Frequently asked questions
What are the factors of 3?
The factors of 3 are 1, 3 — that is 2 factors in total.
How do you find factors of 3?
Test each number from 1 up to 3: if it divides 3 with no remainder, it is a factor. Pair test — every factor pairs with a cofactor, like 1 × 3 = 3.
Why do factors matter for simplifying fractions?
Simplification divides both top and bottom by their greatest common factor — so a shared factor between two numbers, like you can find in the tables above, makes the fraction smaller and cleaner.
