For a number to be divisible by 88 it should be:

Step-by-Step Solution

To determine the divisibility rule for a composite number like 88, we need to factor it into coprime numbers (numbers that have no common factor other than 1).

1. Factor 88:

   • 88 can be factored as 8 * 11.

   • 8 and 11 are coprime because their greatest common divisor is 1.

2. Apply the divisibility rule:

   • If a number is divisible by two coprime numbers, it is also divisible by their product.

   • Therefore, for a number to be divisible by 88, it must be divisible by both 8 and 11.
