# Rule for multiplying by 8

Multiply by 8 just like any other number. For example 3 x 8 = 24. To determine if a number is divisible by 8, just consider the last three digits. For example: 25654789008 is divisible by 8 because the last three digits (008) are divisible by 8 (008 / 8 = 1). 78945987345007 is not divisible by 8 because the last three digits are not divisible by 8 (007 / 8 = 0.875).

Multiplying by 8 is easy when you understand the rule. if you have a number with more than three digits then look at the last three digits if they all go into 8 evenly then the number is divisible by 8. Ex. 56009228. 228 goes into 8 evenly. But for 2 digit numbers if the number isn't even then it automatically doesn't go in. But if it is even

If the answer is even then if the last number goes into 8 then it is divisibly by 8
