4. Factors - a number or algebraic expression that divides another number or expression evenly. Multiples - is the result of multiplying a number by an integer Factor? Multiple?
5. 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.
6. 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
7. 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
8. 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
9. 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.
