You need at least two fractions to determine a least common denominator.
34
There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of two or more fractions.
204
It also called the lowest common factor .... so the L.C.M of 17 and 3 is 51
12,24,36,48,60,72,84,96,108,120......204 17,34,51,68,85,102,119,136,153,170,187,204, LCD for 12 and 17 is 204 (12X17=204)
A common denominator, though not the least, is 1700.

68
It is 85
119
Their product.
34
Their product. If that's 1/2 and 1/7, the LCD is 14.
