Answer 1

Approach 1. Dividing numbers:

One integer A is divisible by another integer B, if after dividing them, A ÷ B, the remainder is zero.

385 is divisible by 7, if there is an integer 'n' such that:

385 = 'n' × 7.

Notice that dividing our numbers leaves no remainder:

385 ÷ 7 = 55 + 0;

So, 385 = 55 × 7;

=> 385 is divisible by 7.

7 is called a divisor (a factor) of 385.
