It is 30 because it's the highest common factor of 60 and 90
The GCF of 60 and 90 is 30.
The highest common factor (HCF) of 15, 60, and 90 is 15. To find the HCF, you need to identify the common factors of the numbers and then determine the highest one they share. In this case, the common factors of 15, 60, and 90 are 1, 3, and 15. Since 15 is the highest common factor, it is the HCF of the given numbers.
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 18.
The GCF is 30.
HCF(160, 90) = 10.
The GCF is 6.
The GCF is 20.
