Using the least common factor, it is found that she will do all the three activities again on the same day again in 48 days.
- She attends dance classes every 6 days.
- She has yoga classes every 16 days.
To find how many days it takes so that she will do all the three activities again on the same days, we have to find the <em>least common factor</em> of 4, 6 and 16.
It is done factoring them using prime factors, then:
4 - 6 - 16|2
2 - 3 - 8|2
1 - 3 - 4|2
1 - 3 - 2|2
1 - 3 - 1|3
1 - 1 - 1
Hence:
lcm(4,6,8) = 2x2x2x2x3 = 48
She will do all the three activities again on the same day again in 48 days.
