Is 90 divisible by 2 3 4 5 6 9 and 10?

Answer 1

no

not by 10 as 216 ends in 6 not 0

same with 5 as does not end in 5 or 0

216 = 2 x 108 = 3 x 72 = 4 x 54 = 6 x 36 = 9 x 24

---------------------------------------

Last digit of 216 is even (one of {0, 2, 4, 6, 8}) so 216 is divisible by 2

6 + 1 + 2 = 9 which is divisible by 3 so 216 is divisible by 3

Last 2 digits are 16 which are divisible by 4, so 216 is divisible by 4

Last digit is not 0 nor 5, so 216 is NOT divisible by 5

216 is divisible by both 2 and 3 so 216 is divisible by 6

6 + 1 + 2 = 9, so 216 is divisible by 9

Last digit is not 0, so 216 is NOT divisible by 10

216 is divisible by 2, 3, 4, 6, 9.

216 is NOT divisible by 5 nor 10.
