What would be the ideal Common Denominator for 2 and 4?
6 is the least common denominator of a set of fractions having 2, 3, and 6 as denominators.
6
There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of a pair of fractions.
The LCD for these two fractions is 6.

2
It is 6
If you're wanting to find a common denominator between fractions with denominators of 3 and 2, then 3 & 2 have only a common factor of 1, so the least common denominator = 2*3 = 6
The least common denominator (I think you mean least common multiple) of 2, 8, and 6 is 24. 24 is perfectly divisible by 2, 8, and 6, leaving no remainder in any case.
Sir/Ma'am, denominator are fractions, so the is no common denominator. But the least common multiples is 30

6 is the least common denominator of a set of fractions having 2, 3, and 6 as denominators.
The answer is 6 beacause 3*2=6.
