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.

252. Their only common factor is 1, so multiply them together: 7 x 4 x 9 = 252.

I'm assuming your talking about the Lowest Common Denominator (LCD) of: 1/3, 1/6, 1/7, and 1/14. You can find the LCD by finding the Least Common Multiple (LCM) of the denominators (3,6,7,14). Idk set way to do that, but its 42

What is the lowest common denominator for two-thirds and three-sixths?

6 the lowest common denominator is the least common multiple of the denominators after both fractions have been simplified as far as possible. 3/6 can be simplified as 1/2. 2/3 cannot be simplified any further. The LCM of 3 and 2 is 6, so the lowest common denominator is 6.
