If you mean 5 different prime factors, there are none. Multiplying the first five primes, you get 2*3*5*7*11 = 2310.
If there is no requirement that the prime factors be different, there are many such numbers, the smallest being 2*2*2*2*2 = 32, and the largest being 2*2*2*5*7 = 280.
No whole number has only three prime factors. At the very least, every number has one as a factor, which is not prime.
One answer is 30. There are others.
105
30, 42, 66, 78, 102, 105, 114, 138 all have exactly three distinct prime factors.
Prime numbers have two factors. Prime squares have three factors. Square numbers have an odd number of factors but that number varies.
No, no prime number has proper factors.
It has three prime factors, but not factors in total.
A composite number.
There are an infinite number of them. 8 has three prime factors, 30 is the first with three distinct prime factors.
A number has exactly three factors if and only if it is the square of a prime number.
A square of any prime number, p has exactly three factors. They are 1, p and p^2.
By definition, a prime number has exactly two factors. So, there are no prime numbers with exactly three factors.
30
There are no prime numbers with three factors. By definition, a prime number has exactly two factors - 1 and itself.
There are an infinite number of them. 8 has three prime factors, 30 is the first with three distinct prime factors.
All prime squares have exactly three factors.49 has exactly three factors: 1, 7, and 49.
How about 105 whose prime factors are 3, 5 and 7
Any composite number. Examples: 4 and 9 . . . (three factors) 6, 8, and 10 . . . (four factors) 12 . . . (six factors) 60 . . . (twelve factors)
A prime number has exactly two factors, one and itself. 25 has three factors: 1, 5, and 25.
