Question

If a number is divisible by both 2 and 3, then the number is also divisible by

• A. 4
• B. 6
• C. 8
• D. 9

Answer 1

The correct option is B 6

According to divisibility rule for 6, if a number is divisible by both 2 and 3, then the number is also divisible by 6.

In other words, we can say that if last digit of a number is an even number and sum of digits of the number is a multiple of 3, then the number will be divisible by 6.

For example, 18 is divisible by both 2 and 3 because its last digit is an even number and sum of digits (1+8=9) is multiple of 3.
so, 18 is also divisible by 6.
