Question 3 (c)

Using divisibility test, determine whether the given number is divisible by 6:
4335

Answer 1

Divisibility rule for 6: If a number is divisible by 2 and 3 both then it is divisible by 6 also.

Applying the above divisibility rule, we get
4335 $\to$ Not divisible by 2 as its units place is not an even number.
$\to$ Divisible by 3 as the sum of its digits (= 15) is divisible by 3.
Since the number is not divisible by both 2 and 3, therefore, it is not divisible by 6.
