Question

How many numbers between 111 and 100100100 (inclusive) are divisible by 333 and 101010?

Answer 1

If the numbers that we are checking divisibility for are between 1-100, there are 3 numbers.

30, 60, and 90 are all divisible by both 3 and 10 because both 3 and 10 are factors of these 3 numbers.
