Question

Using distributive test determine 572 is divisible by 4 ; by 8​

Answer 1

Answer:

As we know the divisibility test of 4 is that the last two numbers shall divide 4 exactly.72 when divide by 4 gives 18 which means that 572 is divisible by 4.

Divisibility test of 8 is that the last 3 numbers must be divisible by 8.So when we divide 572 by 8 we get 71.5 which means 572 is not divisible by 8

Answer 2

Answer:

the divisibility rule of the no. 4 states that if the last 2 digits of a number is completely divisible by 4 , then the number is divisible by 4

therefore, the last 2 digits are 7 and 2

if we do 72/4 , then we will find that 72 is completely divisible by 4 and it will come out to be 18

hence , 572 is divisible by 4

next for 8

the divisibility rule of 8 states that if the last 3 digits of a no. are divisible by 8 completely , then the number is divisible by 8

here, the number is three digit only so we would just divide the whole no.

if we do 572/8 , we will find that it is not completely divisible and it will come out to be 72.5 and hence 572 is not divisible by 8
