This is a lesson plan to strech our conceptions of numbers. Everyone 'knows' that finite numbers do not have infinity as a factor. But the following geometric progression shows otherwise.

All integers except for -1, 0, and 1 have an infinite number of infinities as factors of themselves.

n=(n+1)(Sn) where Sn=1/n to the zero power -1/n to the first power+1/n to the second power-1/n to the third power...+1/n to the infinity power. So here is one factor of infinity in integers.

Now we can multiply the first side of the above equation by (n+1) and multiply the second side by the equivalent expression of (n+2)(Sn+1) and obtain:

We can continue and by this method find the generalized equation of:


and we have an infinite number of infinite factors.
