Is 5 a multiple of 21?
Here we will illustrate two ways to figure out if 5 is a multiple of 21.
One way would be to list all of the multiples of 21 and check if 5 is one of the numbers.
Multiples of 21 are 21, 42, 63, 84, 105, 126, 147, 168, 189, 210 and so on.
Since 5 is not on the list of multiples of 21, the answer to the question "Is 5 a multiple of 21?" is: No.
Another way, would be to simply divide 5 by 21. If the result is a positive integer, then 5 is a multiple of 21.
5 divided by 21 equals 0.238, which is not a positive integer. Once again, the answer to our question is: No.
