Question

using divisibility test determine which of the following number are divisible by 4 and by 8 a ) 4612 b) 9532c) 3516 d) 726352 e) 31795072​

Answer 1

option d and option e are divisible by 4 and 8

Answer 2

Step-by-step explanation:

if we need to know that a number is divisible by 4 , last 2 digits need to be divisible by 4 . if we need to be divisible by 8 then last 3 digits of the number need to be divisible. Hence

(a) 4612 is divisible by 4 but not by 8 as it leaves a reminder of 4 with 8.

(b) 9532 is divisible by 4 but not by 8.

(c) 3516 is divisible by 4 but not by 8.

(d)726352 is divisible by 4 and 8 as 52 is divisible by 4 and 352 is divisible by 8 also.

(e) 31795072 is divisible by 4 and 8 as 72 is divisible by 4 and 8. Hope it helps you.
