HCF is 9 of 63, 108 and 72 numbers when HCF is highest common factor of positive integer.

Given that,

We have to find the HCF of 63, 108 and 72.

We know that,

What is HCF?

The largest positive integer that divides equally into each number with no residual is the greatest common factor (GCF, GCD, or HCF) of a collection of whole numbers.

So,

1,3, 7, 9, 21, and 63 factor the number 63.

1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72 are the factors of the number 72.

1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, and 108 factor the number 108.

Common factors are 1, 3, 9

Then the greatest common factor is 9.

Therefore, HCF is 9
