3 = 1 * 3
9 = 3 * 3
6 = 2 * 3
3 * 1 = 3
12 = 2 * 2 * 3
16 = 2 * 2 * 2 * 2
24 = 2 * 2 * 2 * 3
2 * 2 = 4
and so forth
To have a HCF, you need at least 2 numbers. There is no HCF in just 1 number.
The answer will depend on what kind of sums.
The HCF is 5.
the HCF is 6
The HCF is 1
HCF = 14
The HCF of 16 & 33 is... 1
The HCF is 1.
The HCF is 14.
The HCF is 18
The hcf is 12
The HCF is 7.
