Answer: 30 If those numbers are denominators, the least common denominator is the least common multiple of the three. In this case, 30 is the LCM of 6, 10 and 15, so 30 is the least common denominator.
least common denominator for 15 and 10 is 30, so 9/15 = 18/30 and 7/10 = 21/30
30
The common denominator of 15 and 9 is 45.
The lowest common denominator of 30 and 42 is 210.

Divide numerator and denominator by 2. 30/8 = 15/2
im pretty sure the denominator is the bottom number so the common one would be 3 seeing as how it goes into both numbers. common means a number they share so 3x2=6 3x5=15 3 being the common denominator===========================================That was certainly a delightful bit of reading entertainment.Use a common denominator of 30 .
What is the lowest common denominator of 15 over 57?
The lowest common denominator of 30 and 42 is 210.
A common denominator of 20 and 30 is 600. This is NOT the least common denominator, though.
The common denominator of any two or more whole numbers, such as 10 13 and 15, will always be one (1) because 'common denominator' 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.
