The three numbers are coprime so their LCM = 17*27*37 = 16983
First, find the least common multiple of 4 and 3 (the denominators). This is 12. 3/4 = 9/12 and 2/3 = 8/12 So the revised question is: 9/12 minus 8/12 easy enough? (pssst. the answer is one twelfth)
The LCM is: 84
The LCM is: 16,875
The LCM is: 273

Same as finding the LCM of 6, 5, 7: 2*3*5*7 = 210
I am guessing you mean the least common denominator, which is the LCM of the denominators 4 and 20. The answer is 20.
LCM(5, 4, 3) = 60.
The LCM of 3 4 and 7 is 84.
The LCM of six, four and seven is eighty four.
To find the least common denominator of 3/4 and 3/8, find the LCM of 4 and 8. The answer is 8. Convert 3/4 to 6/8.
LCM(2, 3, 4) = 12.
