There are five whole numbers between 1 and 150 that have exactly 3 different factors. Whole numbers between 1 and 150 with exactly 3 different factors must be the square numbers whose square roots are prime.To find the complete list begin counting... skip 1, not prime; 2 is prime and 2 squared is 4; 3 is prime and 3 squared is 9; skip 4 b/c it is not prime; 5 is prime and 5 squared is 25; 6 not prime; 7 prime and 7 squared is 49; 8 not prime; 10 not prime; 11 prime and squared is 121; 12 is not prime; 13 prime, but squared it is greater than 150. The complete list is 4, 9, 25, 49, and 121. 4 has 1, 2, 4 9 has 1, 3, 9 25 has 1, 5, 25 49 has 1, 7, 49 121 has 1, 11, 121
5,5,7 and 7.
