It is 30 because it's the highest common factor of 60 and 90
30
The GCF of 60 and 90 is 30.
The HCF would be 6
There are infinitely many pairs. One possible pair is 30 and 60.
The HCF of 4 and 90 is 2.
The HCF of 12 and 60 is 12
The GCF is 30.
HCF(160, 90) = 10.
Well, honey, the highest common factor (HCF) of 15, 60, and 90 is 15. It's like finding the biggest number that can divide all three of those numbers without leaving a remainder. So, in this case, 15 is the winner, no ifs, ands, or buts about it.
The GCF is 20.
The GCF is 4.
The GCF is 12.
