Factors of 3

Factors are the mirror image of multiples: they divide into 3 exactly, rather than being built from it. The factors of 3 are 1, 3.

13
Each arc joins a pair of factors that multiply to 3.

Written as pairs: 1 × 3.

Broken all the way down into primes, 3 = 3. Because it has no factors other than 1 and itself, 3 is a prime number.

Common multiples of 3 and other numbers

The lowest common multiple (LCM) of two numbers is the smallest number that appears in both of their multiplication tables. Here is 3 paired with the numbers it is most often compared to.

Pair LCM Greatest common factor Next common multiple
3 and 2 6 1 12
3 and 4 12 1 24
3 and 5 15 1 30
3 and 6 6 3 12
3 and 8 24 1 48

How to find the multiples of 3

Start at 3 and keep adding 3. That gives 3, 6, 9, 12, 15, and the pattern continues for as long as you want to go. Multiplying is simply a shortcut for the same thing: 3 × 7 = 21 saves you counting seven hops one at a time.

How to tell if a number is divisible by 3

A number is divisible by 3 when the sum of its digits is divisible by 3.

Patterns in the multiples of 3

Because 3 is odd, its multiples alternate between odd and even. That alternation is a quick way to sanity-check an answer before you write it down.

The last digits repeat in a cycle of 10: 3, 6, 9, 2, 5, 8, 1, 4, 7, 0, then back to the start. Spotting that cycle is a fast way to rule out a wrong answer.
