I think you mean least common denominator.
7 has no factors (ie, no numbers multiply together to give 7)
7 = 7
6 = 2 x 3
4 = 2 x 2
3 has no factors
3 = 3
5 has no factors
5 = 5
Altogether, we need 2 2's (to have enough for the 4), just one 3 (enough for both the 3 itself and the 6), just one 5 (enough for the 5 itself), and just one 7 (for the 7 itself).
2 x 2 x 3 x 5 x 7 = 420
