The least common denominator would be 50
The least common denominator for 9 and 10 is 90.
The LCD is 10.
least common denominator for 15 and 10 is 30, so 9/15 = 18/30 and 7/10 = 21/30
The least common denominator of 3, 5, and 10 is 30
A common denominator, though not the least, is 40.
A common denominator, though not the least, is 240.
A common denominator, though not the least, is 80.
20
The lcd is the lowest common multiple (lcm) of 10 and 45 which is 90.
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.
A common denominator, though the least, is 240.
