I assume you mean 14, 56 and 84. The HCF of these is 14. The HCF of 1456 and 84 is 28
The GCF is 7.
HCF(10, 84) = 2 HCF(10, 84) = 2 HCF(10, 84) = 2 HCF(10, 84) = 2
84
hcf = 42, lcm = 84.
The GCF is 7.
Since 12 is a factor of 84, it is automatically the GCF.
The GCF is 14.
The GCF is 7
The GCF is 4.
7
The GCF is 24.
