We have that 6 and 4 choose 1, 6 and 8 choose 1, 6 and 10 choose 1.
We proceed as follows:
For 6 and 4 we will have that the least common multiple is 12. Since it can be divided by 6 and equals 2 and by 4 and hat would equal to 3.
For 6 and 8, we will have that the least common multiple is going to be 24. When 24 is divided by 6 it equals to 4 and when 24 is divided by 8 it equal to 3.
For 6 and 10, we will have that the least common multiple is going to be 30. When 30 is divided bby 10 we get 3 and when 30 is divide by 6 we get 5.
