It is 7
hcf = 42, lcm = 84.
The GCF is 2.
The GCF is 7.
The GCF is 42.
Well, let's think about this like a happy little math problem. The highest common factor, or HCF, is the largest number that divides evenly into all the numbers. So, for 42, 49, and 84, the HCF would be 7 because it is the largest number that can divide evenly into all three numbers. Just like painting a beautiful landscape, finding the HCF is about looking for the common thread that brings everything together in harmony.
If you mean: 21, 49 and 84 then the HCF is 7
If you mean 28, 49 and 84 then the hcf is 7
It is: 7
It is: 7
It is: 21
The GCF is 7.7 is the GCF of 42, 49 and 84.
