15 and 30 are common multiples of 3 and 5.
Find their LCM and multiply it by 2 and 3.
The first three common multiples of 2 and 3 are... 6, 12 and 18.
3, 6, and 9 have a greatest common factor of 3.
The first multiple is the LCM of 6, 7 and 8. Then you find LCM*2 and LCM*3.
It is three.
Common multiple of 3 are 3 , 6, 9, 12 Common multiple of 6 are 6,2,3,12

3/83/4 - 3/8 = 6/8 - 3/8 = 3/8Always find the common denominator first when adding or subtracting fractions.
Multiply 11 by 18 and multiply that total by 2 and 3.
Pick two of the fractions and find the Least Common Multiple of those two denominators. Then take that number, and find the Least Common Multiple between that and the third denominator. This number will be the Least Common Denominator between the three fractions.If you don't care to find the Least common denominator, then just take the three denominators, and multiply them together.
