1 is the only common denominator.
The least common denominator of 4 and 5 is the smallest multiple that both numbers share. In this case, the least common denominator of 4 and 5 is simply their product, which is 20. This is because 20 is the smallest number that is divisible by both 4 and 5 without leaving a remainder.
I suggest you do the following: 1) Find a common denominator of 5 and 7. (It need not be the least common denominator; multiplying the two denominators works for our purposes.) 2) Convert both fractions to equivalent fractions with this denominator. 3) Compare the numerators of the fractions thus converted.
LCD(12, 5) = 60
The Least Common Multiple of 3 and 5 is 15, which would be the denominator to use for fractions with the denominators 3 and 5.
Sir/Ma'am, denominator are fractions, so the is no common denominator. But the least common multiples is 30
A common denominator, though not the least, is 30.
The least common denominator of the fractions 3/5 and 5/12 is 60.
60 is the least common denominator of 3 4 5 6 10 and 15.
At least two fractions are needed to determine a common denominator.
A common denominator, though not the least one, is 120.
60
It is: 195
105
The least common denominator is 28.
The least common denominator is 60.
