The LCD of 6, 5, and 7 is 210.
LCD(6, 7) = 42
Assuming you mean the LCM (Least Common Denominator of 2 fractions is the LCM of the denominators, which for 7/1 and 16/1 is 1), the answer is 112.
LCD(7, 5, 10) = 10
5 factors into 1 and 5 6 factors into 2 and 3 Therefore, the least common multiple is 1*2*3*5 = 30 This is what you would use for the LCD, convert the fifths and sixths into thirtieths.
