(1.) 3,123,456

3+1+2+3+4+5+6 = 24

You can divide 24 by 3, but can't divide by 9, therefore 3,123,456 is divisible by 3, but not by 9.

(2.) 3,123,456

6 is even number, therefore the given number is divisible by 2.

6 / 2 = 3 ------> the given number is not divisible by 4, because 3 is odd number.

From (1.) and (2.) -----> the given number is divisible by 6

(3.) 3,123,456 is not divisible by 5.
