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.
126
LCD(9, 21) = 63
252
The answer is 1
63
63
It is: 315
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 LCD (Lowest Common Denominator) of 7 and 9 is 63.
LCD(5, 14) = 70
