Question

Test the divisibility of the following numbers 8:

(i) 8364
(ii) 7314
(iii) 36712

Answer 1

Rule: A number is divisible by 8 if the number formed by its last three digits is divisible by 8.

(i) The given number = 8364
The number formed by its last three digit is 364 which is not divisible by 8.
Therefore, 8,364 is not divisible by 8.

(ii) The given number = 7314
The number formed by its last three digit is 314 which is not divisible by 8.
Therefore, 7,314 is not divisible by 8.

(iii) The given number = 36712
Since the number formed by its last three digit = 712 which is divisible by 8.
Therefore, 36,712 is divisible by 8.
