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
To add three twelfths to three fourths, we first need to find a common denominator. The least common multiple of 12 and 4 is 12. Converting three fourths to nine twelfths, we can now add three twelfths to nine twelfths to get twelve twelfths, which simplifies to one whole. Therefore, three twelfths plus three fourths equals one whole.
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.
