No factors of 5 and 9 are greater than 5 and 9, respectively. 90 is a multiple of 5 and 9 in that range.
80 has 5 factor pairs.
All of the composite numbers less than 100 have factor pairs.
Numbers less than 100 having 19 as a factor are 19, 38, 57, 76, and 95.

50 more than 100 is 150. 100 less than what? You didn't finish.
