There is none because the Least Common Denominator (or LCD) refers to the Least Common Multiple (LCM) of the denominators of two or more fractions or mixed numbers. Even if you converted your whole numbers (x) to their fraction equivalents (x/1), the LCD would always be 1.
675 is the answer. 25 x 27 = 675 and 45 x 15 = 675
225
If by "LCF" you mean "lowest common factor", then that's always ' 1 ',for any pair or larger group of numbers.The greatest common factor of 15 and 45 is 15.
225The LCM is 225.
LCM{45,30,12,8} == 360
The greatest common denominator is infinite. The least common denominator is 45.

It is: 45

The common denominator of 15 and 9 is 45.
The least common denominator of 9 and 15 (if they are denominators) is the least common multiple of those numbers. We denote this the LCD. One way to find that is write the prime factorization of the two numbers. 9 = 3^2 15 = 3 x 5 Take 3^2 x 5 = 9 x 5 or 45 is the LCM of 9 and 15. This is the product of the primes with the largest exponents. So the LCD or least common denominator is the LCM of 9 and 15 and this is 45.
The LCD of 4/5 and 1/3 is 15.
45
No, it's the Greatest Common Factor. LCM is 135
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.
