The least common multiple of 39 and 42 is 13 x 7 x 3 x 2 = 546
We have to remember that this amount is the minor number that can be divided by 39 and 42. I got it as follows:
39.......42 ----> divided by 2 gives:
39.......21 ----->divided by 3 gives:
13........7 ----->divided by 7 gives:
13 .......1 ------>divided by 13 gives:
1........1 ----> we finished!
We just have to multiply all the obtained prime numbers:
13 x 7 x 3 x 2 = 546
That´s it!
Good luck!
