For 17 and 18: 306 For 1/7 and 1/8: 56
The lowest common denominator of any set of whole numbers is 1
1/7 + 3/8 = 8/56 + 21/56 is the lowest common denominator.
Fractions can be simplified when the numerator and denominator have a common factor in them. If both the numerator and denominator have common factors, then we can cancel these factors out. So the simplest for of 18/56 is 9/28.
The lowest common denominator of any two or more whole numbers, such as 56 and 70, 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 lowest common denominator of any two or more whole numbers, such as 56 and 100, 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.

There doesn't appear to be any fractions there but to find the LCD of fractions is done in the same way as finding the lowest common multiple of numbers.
LCD(28, 56) = 56.
