both. can be divisible by 4 and 8

Answer 2

Answer:

a)7328 is divisible by 4 and 8.

b)53056 is also divisible by 4 and 8.

Step-by-step explanation:

a) We know that the divisibility of 4 is checked by checking the last two digits of the number is divisible by 4.

Given the number 7328.

The last digit of the number is 28.We know that 28 is divisible by 4.So,the given number is divisible by 4.

So,7328 is divisible by 4.

We know that the divisibility of 8 is checked by checking the last three digits of the number is divisible by 4.Here the last 3 digits are 328. We find that 328 is divisible by 8.

So, the given number is divisible by 8.

So, the number 7328 is divisible by 8.

b)

53056 - We know that the divisibility of 4 is checked by checking the last two digits of the number is divisible by 4.Given the number 53056. The last digit is 56. We find that 56 is divisible by 4. So the number 53056 is divisible by 4.

We know that divisibility of 8 is checked by checking the last 3 digit if the number is divisible by 8. The last 3 digit is 056.We can write it as 56. We find that 56 is divisible by 8.

So the number 53056 is divisible by 8.
