63
63
The least common denominator is 14. Whenever there are two values, and one is a multiple of the other, the multiple (larger number) is the LCD.
The GCF of 14 and 63 is 7
The LCD for 7 and 9 is 63.
882, because both numbers aren't even and even, or odd and odd, so the lowest LCD it can be is 14 x 63
126
LCD(63, 7) = 63.
LCD(9, 21) = 63
It has to be 7x9 or 63 or less. There is no number less than 63 which is divisible by both 7 and 9 therefore 63 is the LCD.

The answer is 1
252
It is: 315
The LCD (Lowest Common Denominator) of 7 and 9 is 63.
LCD(5, 14) = 70
