Write a number between 80 and 100 that has exactly 4 factors, one of which is 5

Given:
A number between 80 and 100 
That has exactly 4 factors one of which is 5.

I'll choose 90. It is between 80 and 10.

90 ÷ 5 = 18
18 ÷ 6 = 3
3 ÷ 1 = 3

Factors of 90 are: 1, 3, 5, and 6.

  1 x 3 =   3 
  3 x 5 = 15
15 x 6 = 90

1 x 3 x 5 x 6 = 90

I’m not sure i’m sorry
