There is none because Least Common Denominator (or LCD) refers to the Least Common Multiple (LCM) of the denominators of two or more fractions or mixed numbers. Even if you converted your whole numbers (x) to their fraction equivalents (x/1), the LCD would always be 1.
It is: 420
least common denominator for 15 and 10 is 30, so 9/15 = 18/30 and 7/10 = 21/30
40
The Least Common Denominator of 5, 7, and 35 is 1.
The least common denominator (LCD) is 40.
70
It is: 420
The least common denominator would be 50
least common denominator for 15 and 10 is 30, so 9/15 = 18/30 and 7/10 = 21/30
40
It is: 630
Least common denominator of 7 and 5 is 35.
The Least Common Denominator of 5, 7, and 35 is 1.
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.
7
The least common denominator is 38*7 = 266.
