The best common denominator for 5, 7, and 8 is 280. To find the least common multiple (LCM) or the least common denominator (LCD) of a set of numbers, you need to find the smallest number that is divisible by all the numbers in the set. In this case, the prime factorization of the numbers 5, 7, and 8 are 5, 7, 2 x 2 x 2. To find the LCM, you take the highest power of each prime factor that appears in any of the numbers, resulting in 5 x 7 x 2 x 2 x 2 = 280.

DevinThe common denominator of any two or more whole numbers, such as 5 7 and 8, 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.
