You were on the correct path in the beginning, so it was 100%. You then had a fork of two ways, and taking one randomly leaves you with a 50% chance of being on the right track. The second fork cuts your chances in half again, so 25%. There is a 25% chance you are still on the correct path.

Step-by-step explanation:
it is a multiple of 21.
the highest common factor of 2 numbers is the longest combination of prime factors they have in common.
the prime factors of 21 are simply
3×7
if another number A shares this as the longest combination of prime factors, that means it contains 3×7 itself in its prime factors.
and that means this number A can only be a multiple of 3×7 (= 21), as other prime factors present would be the factor of 21.
