Factors - a number or algebraic expression that divides
another number or expression evenly.
Multiples - is the result of multiplying a number by an
integer

Divisibility Rules
Divisibility rules tells whether a number is exactly
divisible by other numbers. This rule is a shortcut way to
decide whether a number is exactly divisible to another
number without doing division computation.

Divisible by 4
- if the last two digits form a number that is divisible by 4.
Also, numbers ending in two zeros are divisible by 4.
Example:
400 240 480 1000

Divisible by 8
- if the number formed by the last 3 digits is divisible by 8. Also,
a number ending in three zeros are also divisible by 8.
Example:
6000 992 480 296

Divisible by 12
- If the number is divisible by both 3 and 4.
Example:
756 7+5+6=18 divisible by 3
756 56 ÷ 4 = 14 divisible by 4
Therefore, 756 is divisible by 12

Divisible by 11
- If the sum of the digits in the odd places and the sum of
the digits in the even places are equal or their difference is a
multiple of 11, then the number is divisible by 11.
Example:
1364 1+6=7
1364 3+4=7
Then, 1364 is divisible by 11.
