You need at least two numbers to find a GCF.
The GCF is 15.
The GCF is 6.
It is: 12
60
The GCF is 42.
The greatest common factor of the numbers '420' and '2646' is '42'.
The GCF is 70.
42=2x3x7 56=23x7 so the HCF = 2x7 = 14
The GCF is 10.
6
hcf = 42, lcm = 84.
The GCF is 42.
It is: 14
The GCF is 42.
The GCF is 42.
the HCF is 6
The HCF is 14.
The HCF of 12 and 60 is 12
The GCF is 21.
7
The GCF is 14.
