I'm not sure if you got the right abbreviation of that term.
LCD = Least Common Denominator = 1
GCD = Greatest Common Denominator = 17
LCM = Least Common Multiple = 34
Tough to tell exactly what that is. The LCD of 8 and 5 is 40.
120
12
6/11 and 9/11 LCD
1/3 and 3/8 have a lcd of 24 (8/24 and 9/24)
You need at least two fractions to find something in common.
If that's 84 and 35, the LCD is 420.If that's 8/4 and 3/5, the LCD is 20.
The Greatest Common Factor of 12, 15 is 3.
Assuming you mean the LCM (Least Common Denominator of 2 fractions is the LCM of the denominators, which for 7/1 and 16/1 is 1), the answer is 112.
1/3 and 3/8 have a lcd of 24 (8/24 and 9/24)
LCD(15, 7, 8) = 840.
1/3, 3/4, 5/32, 8/9The LCD is 288.
30
LCD(8, 3) = 24.
You need at least two fractions to find something in common.
It is 8
LCD(8, 15) = 120
The LCD of 3/8 and 1/4 is 8.
The LCD of 1/3 and 1/8 is 24.
The LCD for working with those fractions is 8 (or 1/8)
