The GCF is 25.
The greatest common factor of 175 and 250 is 25.
The greatest common denominator, like the greatest common multiple, is infinite.
LCD (lowest common denominator) refers to fractions and your question did not include any fractions. However, assuming that you're looking to reduce 75/275, the answer is 3/11.
3000
A common denominator is 75.
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.
75/175 = 3x25/7x25 = 3/7
There is no greatest common multiple, as the multiples are infinite. Their greatest common denominator is 15. Their lowest common multiple is 7650.
9 over 15. You divide them both by a common denominator in this case 5.
There is no such thing as a most common denominator.
A common denominator, though not the least, is 7500.
It is any multiple of 75.
It is 75.
the lowest common denominator is 75 13/15 = 65/75 22/25 = 66/75 so 22/25 is bigger
LCD(75, 275) = 825
