Is 91 a multiple of 3?

Answer 1

No, 91 is Not a multiple of 3.

An easy way to determine if a number is a multiple or divisible by 3 is to add up all its

digits and see if the sum is divisible by three.

For example: 321 , 3 + 2 + 1, Therefore 321 is divisible by 3 or a multiple of 3.

Unlike the number 131, 1 + 3 + 1, whose digits sum up to 5, which isn't divisible by 3.

So therefore, 91 is 9+1 Therefore 91 is not a multiple of 3.
