Using the least common factor, they need to wait 14 days until they next get to work together.
To find the time that passes between the events happening at the same time, we need to find the least common multiple of the periods.
In this problem, the periods are of 2 days and 7 days, which already are prime numbers, hence:
lcm(2,7) = 2 x 7 = 14.
They need to wait 14 days until they next get to work together.
