Their LCM which is 693 (9 x 7 x 11).
Least common denominator of 7 and 5 is 35.
It is 48
The Least Common Denominator of 5, 7, and 35 is 1.
LCD(7, 11, 12) = 924
7
The least common denominator is 38*7 = 266.
these are all prime numbers so if they are denominators, the least common denominator would be their product. 5x7x9x11 = 3465
The common denominator is 28.
