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

The relationship between the input and output values can be determined by a mathematical function or rule. In this case, when the input is 1 and the output is 8, the rule could be represented as f(x) = 8x, where f(x) is the function and x is the input value.
