There is none because 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 lowest common denominator of 15 over 57?
The Least Common Denominator of 57 and 35 is 1.
LCD(117, 38) = 4446.
57
It is 117
Denominator of 117 is 1
456
117
The LCD for 19 and 3 is 57
The greatest common denominator (gcd) of 42 and 117 is 3. So 3 is the only factor of both.
The common denominator of any two or more whole numbers, such as 9 and 13, 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.
Simple Answer: 1 hour and 57 minutes. Detailed Answer: Sixty goes into 117 once, remainder 57. Thus, it is one hour, 57 minutes. That is, 117 minutes after noon would be 1:57 pm.
