Rosa claims the longest string of prime factors for 30 is 2x3x5. tyee claims there is a longer string, 1x2x1x3x1x5. who is correct why?

Rosa is correct, as 1 is not considered a prime no.

29. because you will divide each number of months by 12 to find the number of years. which would mean, 5, 12.5, 16, 45, 50, 72.5. which is crazy. anyhow, i think you find the median in the middle. and yea hope your test goes good
