The least common denominator is 24.
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.
What is the least common multiple of 8, 7, and 2? the answer is 56
LCD(28, 56) = 56.
It is: 728
56
4536
7560
As 2 is a factor of 56, lcd(2, 56) = 56.
1/7 + 3/8 = 8/56 + 21/56 is the lowest common denominator.
