One.
The number of zeros is determined by how many times 12 divides into 15!. To determine this, since 12 = 22*3, we will look at how many times 2 and 3 divide into 15!. 2 divides 2,6,10,14 once, 4,12 twice, and 8 three times, so that 2 divides 15! exactly 11 times. 3 divides 3,6,12,15 once and 9 twice, so that 3 divides 15! exactly 6 times. From this, we can see that 12 divides into 15! exactly 5 times, since 125=210*35. In other words, the base-12 representation of 15! ends in 5 zeros.
Because 3 is the largest number that divides into both 12 and 15 evenly with no remainder.
It is: 15-12-8 = -5
62
7/12+8/12 = 15/12 15/12 = 5/4 or 1.25
The LCM of 8, 12 and 15 is 120 because 120 is the smallest whole number that 8, 12 and 15 will all divide into evenly with no remainder.
The Least Common Multiple of 8, 12, 15 is: 120
The LCM is 120.
5/12 + 8/15 = 19/20
Not sure what an lmc might be but LCM(12, 15, 8) = 120
