- Homework Statement
- In the Balinese calendar, to specify a day, it is sufficient to specify the position of the day in just the five, six, and seven day weeks. Thus, we specify a day by the notation (a_5,b_6,c_7) where a is a number from one to five, b is a number from one to six, and c is a number from one to seven. Find the minimum number of days between the day (2_5,3_6,5_7) and (5_5,2_6,4_7)

- Relevant Equations
- none, I think

I'm not sure how to solve this. I think that we can count - to get from 2_5 to 5_5 is 3_5 days. And to get from 3_6 to 2_6 is 5_6 days. From 5_7 to 4_7 is 6_7 days. But, how do I put this together to find the minimum number of days? Is it the lowest common multiple of 3,5, and 6? (Which is 30)?
