no, factors of a number would be less than that of the original number. A prime number is a number that has factors of only itself and 1.
How about 105 whose prime factors are 3, 5 and 7
By definition, a prime number has exactly two factors. So, there are no prime numbers with exactly three factors.
It is 97 which has only two factors because it is a prime number
A number is prime if its only two factors are one and itself.

Numbers can be checked to see if they are primes simply by factoring them. Every prime number has exactly two factors, 1 and the number itself. If there are more or less than 2 factors, the number is not a prime. 1 has only one factor so it is not a prime, and composite numbers have 3 or more factors.
512 = 29 or 768 = 28*3 have 9 prime factors each.
Well, darling, the number you're looking for is 15. It's less than 20, odd, and can be broken down into the prime factors 3 and 5. So, there you have it, a prime factor party with the number 15 strutting its stuff.
