Question

123,456 is not divisible by which of the following numbers? 3,4,5,6

Answer 1

The answer is 5 because for it to be divisible by 5 the number needs to end in 0 or 5.
Also 3 goes into that number 41152
4=30864
6= 20576
5= 24691.2
because of the .2 at the end it is not divisible.

so the answer is 5
