Answer:

The answer is 5.

Explanation:

15:3×5

20:2×2×5

In both 15 and 20, '5' is in common. So, the numbers which are in common are called HCF ( Highest Common Factor ).

So, the HCF (well known as GCF ) of 15 and 20 will be 5.

I hope this helped you. If this helped you please mark this answer as brainliest because, I want to go in virtuoso rank and I still need 3 more points.
