6 and 10 2x3=6 2x5=10 HCF=2 LCM=30
None. But 4 and 6 have a LCM (not LMC) of 12 and HCF of 2.
The GCF is 2.
6 and 8
6 and 36 12 and 18
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
Oh, dude, the Highest Common Factor (HCF) of 6 and 30 is like the biggest number that can divide both of them without leaving a remainder. So, you look at the factors of 6 (1, 2, 3, 6) and 30 (1, 2, 3, 5, 6, 10, 15, 30) and find the biggest one they have in common. In this case, it's 6. So, the HCF of 6 and 30 is 6. Easy peasy, lemon squeezy!
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.
