Answer 1

the write answer is 78728

Answer 2

Answer:

78728 is divisible by 8 in this problem.

Step-by-step explanation:

The general rule for the divisibility of 8 is given below:

"If the number formed by the last 3 digits of the given number is divisible by 8, the whole number is also divisible by 8."

Applying this rule, we can say that the numbers 78728 is divisible by 8; and 6288 is not.

Another simple and common rule: As the multiples of even numbers are always even, odd numbers are not divisible by even ones.

As 8 is an even number and the first 2 numbers given are odd, we can say that they are not divisible by 8.

Therefore, only 78728 is divisible by 8 in the given problem.
