If he got all three today, he will get all 3 newsletters in the next 40days
<h3>Least common multiple</h3>
- Sports = every 5 days
- Model rail roads = every 10 days
- Music = every 8 days
Find the least common multiple of 5, 10 and 8
- 5 = 10, 15, 20, 25, 30, 35, 40, 45, 50
- 10 = 20, 30, 40, 50, 60
- 8 = 16, 24, 32, 40, 48, 56
The least common multiple of 5, 10 and 8 is 40
