Prime numbers have two factors.
There are infinitely many numbers which have 6 prime factors.
Between 1 and 10, 2, 3, 5 and 7 are already prime numbers. 4 (2x2), 6 (2x3), 8 (2x2x2) and 9 (3x3) can be represented as a product of prime factors, i.e. four natural numbers between 1 and 10 can be represented as such.
21 has two prime factors.
The prime factors are: 2, 5
The prime factors of 200 are 2 and 5 or as a product of its prime factors 2*2*2*5*5 = 200
Prime numbers have two factors.
Two of them and as a product of its prime factors: 2*2*2*2*5*5*5 = 2000
Two of the factors of 80 are prime numbers: 2 and 5.
All prime numbers have only two factors
This can be an extension to the proof that there are infinitely many prime numbers. If there are infinitely many prime numbers, then there are also infinitely many PRODUCTS of prime numbers. Those numbers that are the product of 2 or more prime numbers are not prime numbers.
There are infinitely many numbers which have 6 prime factors.
The prime numbers (factors) of 1000 are: 2 and 5
Three. The prime numbers (factors) of 120 are: 2,3,5
Three. The prime numbers (factors) of 60 are: 2,3,5
Between 1 and 10, 2, 3, 5 and 7 are already prime numbers. 4 (2x2), 6 (2x3), 8 (2x2x2) and 9 (3x3) can be represented as a product of prime factors, i.e. four natural numbers between 1 and 10 can be represented as such.
