It is: 12
The hcf of 60 and 72 is 12
6. 72/6=12 78/6=13
6. 42 = 2 x 3 x 7 18 = 2 x 32 72 = 23 x 32 hcf = 2 x 3 = 6
The HCF is: 2The LCM is: 2,520
The GCF is 12.
The GCF is 12.
hcf(72, 12) = 12
12
It is: 12
The hcf of 60 and 72 is 12
HCF of 12 and 18 is 6 and LCM of 108 and 72 is 216 So: 6 times 216 = 1296
6. 72/6=12 78/6=13
The greatest common factor of 28 and 72 is 4.
4 is a common factor of 12, 32 and 72. Here is the proof: 12/4=3, 32/4=8, 72/4=18
LCM = product/HCF; HCF is 6 so LCM = 12 x 42 = 504
The HCF of 48 and 72 is 24. The LCM is 144.
