How do I find if a number is a multiple of 8?

Answer 1

Riley Anderson

Please see the process and reason below.

Just check the last three digits of the number.

If they are divisible by #8#, the entire number is divisible by #8#.

For example, last three digits of #53927592# are #592# and they are divisible by #8# as #592=74xx8#.

Hence, #53927592# is divisible by #8# and #53927592=6740949xx8#.

The reason is that as the number can be expressed as #YYYYYZ Z Z=YYYYYxx1000+Z Z Z#

= #YYYYYxx125xx8+Z Z Z#.

As #YYYYYxx125xx8# is divisible by #8#, if #Z Z Z# is divisible by #8#, #YYYYYZ Z Z# is divisible by #8#.

A number is a multiple of 8 if it can be evenly divided by 8 without leaving a remainder. You can determine this by checking if the number is divisible by 8. If dividing the number by 8 results in an integer quotient, then the number is a multiple of 8. Otherwise, it is not a multiple of 8.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
