There is none because the 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

84/14 = 6 84/7 = 12 84/3 = 28 Hence 84 is the least common denominator

84/14 = 6 84/7 = 12 84/3 = 28 Hence 84 is the least common denominator
The least common denominator of fractions is the smallest multiple of the denominators that they both share. To find the least common denominator of 2/3 and 7/12, you need to find the least common multiple of 3 and 12, which is 12. Therefore, the least common denominator of 2/3 and 7/12 is 12.
For 7/12 and 7/15 the LCD is 60.
Least common denominator of 7 and 5 is 35.
The Least Common Denominator of 5, 7, and 35 is 1.
It is 48
