LCM is least common multiple, so start by factoring 24. 24's factors are: 1, 2, 3, 4, 6, 8, 12, and 24. So two of these numbers have to have a HCF (or highest common factor) of 2 to be the answer. You can rule out 1 and 3 because 2 isn't a factor. Then start listing out the multiples. Remember that 24 has to be the lowest multiple the two numbers have in common. 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24 4, 8, 12, 16, 20, 24 6, 12, 18, 24 8, 16, 24 12, 24 24 6 and 8 OR 8 and 12 OR 12 and 24 are the two here whose least common multiple is 24. But 6 and 8 are the only pair whose HCF is 2.
the hcf of 12 and 20 = 4
The highest(or greatest) common factor is the highest number that divides exactly into two or more numbers. 16: 1, 2, 4, 8, 16 24: 1, 2, 3, 4, 6, 8, 12, 24 The greatest common factor of 16 and 24 is 8.
Since 12 is a factor of 24, it is automatically the GCF.
The hcf is 12
The HCF is 4. 16/4 is 4, 12/4 is 3

If you mean 24 and 36 then the HCF is 12
