The LCD of 4/5 and 1/3 is 15.
135 is the lowest common denominator of numbers 27 and 45.
The Greatest Common Factor of 15, 45: 15The Least Common Multiple of 15, 45: 45
The Least Common Multiple (LCM) for 27 45 10 is 270.
The LCM of 45 and 50 is 450.Least Common Multiple (LCM) for 50 45 is 450.
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.
The greatest common denominator is infinite. The least common denominator is 45.
The least common multiple is 1440
If I wanted to be nasty about it, I would say 1, because the least common denominator of 45/1 and 75/1 is 1. The least common denominator of two fractions is the least common multiple of their denominators. I presume you are asking for the least common multiple of 45 and 75, which is 225.
