Write your answer...

A common denominator, though not the least, is 40.

It is 10

80

The least common denominator for 9 and 10 is 90.

The least common denominator of 3, 5, and 10 is 30

A common denominator, though not the least, is 240.

A common denominator, though not the least such, is 80.

A common denominator, though not the least, is 80.

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.

20

A common denominator, though not the least, is 80.

A common denominator, though the least, is 240.

There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of a pair of fractions.

10

If you mean Least Common Multiple; it is 50.

The least common denominator of 2 and 5 is 10.

A common denominator of 6, 8 and 10 is 480. This is NOT the least common denominator, though.

The least common denominator (LCD) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question! The least denominator for a number is itself.
