Question 856669: How many different ways can 700 be expressed as the product of two positive integers?
I think I started it correctly but I'm not sure if I have all of them; is there an easy way to answer this question?

Start by factoring 700 into its prime factors
700 is even so you know 2 will be one of the prime factors
2*2*5*5*7
also remember that 1 is always a factor
now we can write all the two positive integers using the prime factors
to construct them
(2, 350)(4, 175)(20,35)(100,7)(1,700)(25,28)(70,10)(5,140)
