Explanation

The factors of 10 are 1 & 10, and 2 & 5. Since there are four factors, Quantity A is 4.

The prime factors of 210 are 2, 3, 5, and 7:

Factorisation is the quickest way to solve it. Since after the factorisation of 10, we'll already have the prime factors of 10, we just need to factorize 21 to get the count for 210.
