80
240
the LCD of fractions is the least common multiple. So we are looking for the least common multiple of 16 and 20 which is 20. So the Least common denominator is 80
The LCD of 4 and 16 would be 4.
LCD(16, 23) = 368
lcd of 18 and 16 = 144
LCD(11, 16) = 176
The LCD of 16 and 8 is 16, because 8 and 16 are both factors of 16.
The LCD of 20 and 9 is 180.
LCD(12, 20) = 60
Assume an additive expression.X5 + X3X3(X2 + 1)--------------------so,X3====Is the LCD
LCD(8, 16, 64) = 64
