945 is the lowest common denominator. 3 is the greatest common factor.

1/7 + 3/8 = 8/56 + 21/56 is the lowest common denominator.
The lcm, or lowest common multiple of 21 and 17 is 357.
Factor each number to see if they have common factors:21 = 3*736 = 3 *12The LCD is, 36*7 or 21*12, 252.

The lowest common denominator is 21.
LCD(8, 21, 7) = 168.
The greatest common denominator of any set of integers is infinite.
1/7 + 3/8 = 8/56 + 21/56 is the lowest common denominator.
The lcm, or lowest common multiple of 21 and 17 is 357.
2 21/100 Since 21 can be divided by 3 and 7 (lowest primes), but 100 cannot, then logically, 100 is the lowest common denominator for this, therefore 21/100
