Generally when we find Least common denominator,

If the any denominator number of them is not multiple of other denominator, then you just multiply the denominator numbers.

Given fractions are 1/7,1/8 and 6/11.

7*8*11 = 616

Least common denominator of given fractions is  616.

Write the prime factorization of each denominator.

7 = 1*7*3 = 71

8 = 2*2*2= 23

11 = 1*11= 111

Multiply highest power of each factor in the either number.

L.C.D =23*71*111

           = 616
