LCD(63, 7) = 63.
63
63
The LCD (Lowest Common Denominator) of 7 and 9 is 63.
63
It is: 63
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.
63...so it would be 56/63 and 36/63
The LCD for 7 and 9 is 63.
If you mean lcm, it is 36 because 9 x 4 equals 36 and 3 x 12 equals 36.

There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of two or more fractions. Even if you converted your numbers (x) to their fraction equivalents (x/1), the LCD will always be 1.If the 7 and 9 are denominators, the LCD is 63.
