To find the next day the three will work together, look for the least common multiple of 2,4,5. Multiples of 5 are (5,10,15,20,25), while 4 has multiples of (4,8,12,16,20), and 2 has all even multiples. The least number that is found in all three sets would be 20, so the three employees will work together again in 20 days.
