A single number cannot have anything in common. To find a lowest common denominator, you need to be adding or subtracting at least two fractions.
The least common multiple of the numbers 17 and 13 is 221.

LCD(17, 19) = 323
The least common multiple of 7, 14, and 17 is 238.
If that's least common denominator, no. The LCM of 9 and 17 is 153.
I'm not sure if you got the right abbreviation of that term. LCD = Least Common Denominator = 1 GCD = Greatest Common Denominator = 17 LCM = Least Common Multiple = 34
A common denominator, though not the least, is 1700.
You need at least two fractions to determine a least common denominator.
Their product. If that's 1/2 and 1/7, the LCD is 14.
