Using the divisibility test, determine is divisible by or not?
Step 1: Explaining the divisibility test:
Divisibility test of : A number is divisible by , when the number is divisible by both and
Divisibility test of : A number is divisible by , when the number is ending with
Divisibility test of : A number is divisible by , when the sum of the digits of the number is divisible by
Step 2: Finding whether is divisible by or not:
The given number is
is ending with , therefore is divisible by
Sum of the digits of
is not divisible by , therefore is not divisible by .
As, is divisible by but not by .
Hence, is not divisible by
