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.
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.
the number is 350 the factors is 175 and 2
How about 105 whose prime factors are 3, 5 and 7
If you're allowed to repeat factors, 2 x 2 x 2 x 2 = 16. If not, no number less than 100 has more than 3 distinct prime factors.
30 does.

A number is prime if its only two factors are one and itself.
It is 97 which has only two factors because it is a prime number
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.
