A common denominator, though the least, is 260.
The lowest common denominator of any two positive numbers is always 1.
A common denominator of 20 and 30 is 600. This is NOT the least common denominator, though.
The common denominator of 9 and 13 is 1
13 = 1 x 13, 20 = 2 x 2 x 5. There are no common factors so the LCM is the product, ie 260.
The least common denominator of 13 and 52 is52

The least common denominator of 3 and 13 is 39.
The least common denominator of 13 and 52 is52
A common denominator, though not the least one, is 12*20 = 240.
The lowest common denominator is 40 5/8 = 25/40 13/20 = 26/40 so 13/20 is bigger
20
The answer is 20
The LCM is 52
The least common denominator (LCD) is 1.
