The lowest common denominator of any two or more whole numbers, such as 7 and 17, will always be one (1) because 'common denominator' refers to the denominators of two or more fractions or mixed numbers, not whole numbers. So, a set of whole numbers (x,x) would have to be converted to their fraction equivalents, i.e., x/1, which will always yield a denominator of 1.
The word "lowest" is a superlative. Being a superlative means that there can be only one such number so asking about lowest common denominators is nonsense. The lowest common denominator is 102172070.
1/2 , 3/4 , 7/8. The denominators are 2, 4, and 8. The lowest common multiple of these numbers is 8. This becomes the lowest common denominator.
The least common multiple of 7, 14, and 17 is 238.
For 17 and 18: 306 For 1/7 and 1/8: 56

It's already reduced as 7 and 17 do not have common factors (except 1 of course).

The easiest way to find a common denominator of two numbers is to multiply them. Therefore, one of the common denominators for 6 and 7 would be 42 (7 x 6). This method will not necessarily produce the lowest common denominator, but it will determine one. For example, multiplying 4 and 6 will give you 24 as a common denominator. However, the lowest common denominator for 4 and 6 is 12.
The lowest common denominator of any two or more whole numbers, such as 12 7 9 and 6, will always be one (1) because 'common denominator' refers to the denominators of two or more fractions or mixed numbers, not whole numbers. So, a set of whole numbers (x,x) would have to be converted to their fraction equivalents, i.e., x/1, which will always yield a denominator of 1.

The Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of a pair of fractions. I assume the 7 and 21 are the denominators of two fractions you need to add or subtract.LCD(7, 21) = 21.
Lowest common multiple of 2 and 7 is 14.
