well one way is to multiply them together and you get 120 or you could count up by the largest one until they all go into it for example
6
12
18
24
30
36
42
48
54
60
hint look at the ones that end in 5 or 0 so 5 can go into them and then see if the other one can go into it
in this case 60 is the best answer

RafaThe common denominator of any two or more whole numbers, such as 6 5 and 4, will always be one (1) because 'common denominator' refers to the denominators of two or more fractions or mixed numbers, not whole numbers. So, a set of whole numbers (x,x) would have to be converted to their fraction equivalents, i.e., x/1, which will always yield a denominator of 1.

What are two common denominators for 3 over 8 and 5 over 6?
24 and 48 are two possible common denominators for 3/8 and 5/6.
Least common denominators?
8/9, 5/12, 6/7
What is one sixth plus four sixth?
1/6 + 4/6 = 5/6. This is correct because both the fractions have common denominators, therefore, all you have to do is add the numerators.
What is the largest common denominator for 7 and 5 and 6?
do you mean smallest there's a whole bunch of large common denominators for 7,5 and 6
Why can't you add fractions with unlike denominators?
You cannot add fractions with different denominators because they do not represent the same size parts of a whole. (A half is larger than a third, so you cannot add them together as equals until they are expressed with the same denominator.)When fractions have like denominators, we add the numerators and place them over the denominator, for example:2/7 + 3/7 = (2 + 3)/7 = 5/7We can add fractions with unlike denominators by finding their "least common denominator". For example: 2/3 + 5/6 can both be expressed in terms of a least common denominator (6). Multiply the numerator and denominator by the same number to convert the fraction.2/3 + 5/6 -- multiply the numerator and denominator of 2/3 by 2, and 2/3 = 4/64/6 + 5/6 = 9/6 or 11/2Another example : a common denominator for 3/4 and 1/5 would be 20and 3/4 = 15/20 [ (3 x 5)/(4 x 5) ]while 1/5 = 4/20 [ (1 x 4)/(5 x 4)So 3/4 plus 4/5 would become 15/20 + 4/20 = 19/20.
