Quick Divisibility Rules

Divisibility by 2
A number is divisible by two if it is even — if the last digit is 0, 2, 4, 6, or 8.

Divisibility by 3

A number is divisible by three if you add all its digits and the sum is divisible by 3.
You can repeat this process if the sum of the digits has two or more digits. For example: 357 → 3 + 5 + 7 = 15 → 1 + 5 = 6 → divisible by 3

Divisibility by 4
A number is divisible by four if one-half of its last two digits is even.

Divisibility 5
A number is divisible by five if its last digit is 5 or 0.

Divisibility by 6
A number is divisible by six if it is divisible by 3 and it is even.

Divisibility by 9

A number is divisible by nine if you add all its digits and the sum is divisible by 9.
You can repeat this process if the sum of the digits has two or more digits. For example: 981 → 9 + 8 + 1 = 18 → 1 + 8 = 9 → divisible by 9

Divisibility by 10
A number is divisible by ten if its last digit is 0.

Divisibility by 12
A number is divisible by twelve if it is divisible by 3 and 4.

Divisibility by 15
A number is divisible by fifteen if it is divisible by 3 and 5.
