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.
The Least Common Multiple (LCM) of 5, 15, and 75 is 75.
The Least Common Multiple of 75, 105 is 525.
Since the lowest common multiple of 3 and 5 is 15, the common multiples of 3 and 5 are the multiples of 15: 30, 45, 60, 75, 90, etc...
The least common multiple of 30 , 75 , 60 , 90 = 900
