The question - with the second alternative - is tautological (m = n).
The product is positive
Either it is a prime or put m = n! Is that it?
As a product of its prime factors: 2*2*2*5 = 40 or as 23*5 = 40
The product of two prime numbers can never be another prime number, the numbers that you multiplied are factors of the product. (example, 9 times 5 is 45, 9 and 5 go into 45)
As a product of its prime factors: 5*7*11 = 385
22 is a composite number because it can be produced from the product of 2 times by 11.Prime numbers are ones that are the product of themselves times by one alone example 3 is a prime cos' it is 3 times 1 only this alone.It's a composite number. It cannot be prime because it is divisible by two.
How about: 3*5 = 15 as a product of its prime factors
3 times 13
5 times 37
As a product of its prime factors: 7*13 = 91
12
As a product of its prime factors in exponents: 2^4 times 5^5 = 50,000
