None. But 4 and 6 have a LCM (not LMC) of 12 and HCF of 2.
The GCF is 2.
6 and 8

HCF(8, 6) = 2.
The GCF is 2.
6 is the HCF of 18 & 48

6 and 10 2x3=6 2x5=10 HCF=2 LCM=30
It is 2
12 = 2 x 2 x 3 16 = 2 x 2 x 2 x 2 HCF=2 x 2 = 4 HCF = 4
Factor them. 2 x 2 x 2 x 3 = 24 2 x 3 x 5 = 30 Select the common factors. 2 x 3 = 6, the GCF.
The GCF is 2.
factors of 8: 1, 2, 4, 8 factors of 18: 1, 2, 3, 6, 9, 18 HCF: 2
None. But 4 and 6 have a LCM (not LMC) of 12 and HCF of 2.
