The common denominator of any two or more whole numbers such as 20 and 28 will always be one (1) because common denominators refers to the denominators of two or more fractions or mixed numbers, not whole numbers. So, a set of whole numbers (x,x) would have to be converted to their fraction equivalents, i.e., x/1, which will always yield a denominator of 1.
The common denominator is 28.
7
The LCD of both numbers is 28
20/28Divide both the numerator and denominator by 420/28 = 5/7
There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of a pair of fractions.
LCD(20, 28) = 140
A common denominator of 20 and 30 is 600. This is NOT the least common denominator, though.
The lowest common multiple, or lowest common denominator, of 18 and 28 is 252.
The common denominator is 28.
least common denominator of 26 42 and 28 is 1092.
least common denominator of 36 42 and 28 is 252.
7/15 = 28/60 19/20 = 57/60
A common denominator, though not the least one, is 12*20 = 240.
A common denominator, though the least, is 260.
20
The answer is 20
The greatest common denominator of any set of denominators is infinite.
