The least common denominator of three fourths and five sixths is twelve.

The LCD of 3/4 and 7/9 is 36.

Answer: 30 If those numbers are denominators, the least common denominator is the least common multiple of the three. In this case, 30 is the LCM of 6, 10 and 15, so 30 is the least common denominator.

The LCM applies to whole numbers, not fractions. If you're trying to find the least common denominator, it's 12.

Answer: 30 If those numbers are denominators, the least common denominator is the least common multiple of the three. In this case, 30 is the LCM of 6, 10 and 15, so 30 is the least common denominator.

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.

16 is the common denominator. 3/4=12/16 7/16=7/16 5/8=10/16
