HCF(10, 84) = 2 HCF(10, 84) = 2 HCF(10, 84) = 2 HCF(10, 84) = 2
hcf = 42, lcm = 84.
The GCF is 28.
The GCF is 7.
Since 12 is a factor of 84, it is automatically the GCF.
The GCF is 24.
7
The GCF is 7.
The GCF is 2.
Oh, what a happy little question! The highest common factor (HCF) of 21, 42, and 84 is 21. You see, 21 is the largest number that can evenly divide all three of these numbers, creating a harmonious relationship between them. Just like adding a touch of white to a painting to bring all the colors together, finding the HCF helps us see the beautiful connection between these numbers.
The GCF is 7.
If you mean 28, 49 and 84 then the hcf is 7
