Sears has a sale on mechanics tool chests every 40 days and a sale on mechanics tool sets every 60 days. If both are on sale today, how long will it be before they are on sale together again?
-----
Using prime-factor method of finding the least common multiple:
40 = 2^3*5
60 = 2^2*3*5
-------
lcm = 2^3*3*5
lcm = 8*15
lcm = 120 days
