What least number must be added to 1056 so that the sum is completely divisible by 2, 3 and 5?

Given: Added to 1056 so that the sum is completely divisible by 2, 3 and 5.

The least common multiple (LCM) of 2, 3, and 5 is:

LCM(2, 3, 5) = 30

The next multiple of 30 after 1056

We divide 1056 by 30:

1056 ÷ 30 = 35.2

The next whole number after 35.2 is 36

Now multiply 36 × 30 = 1080

We need to add to 1056 to reach 1080

1080 − 1056 = 24

Thus, correct option is (a).
