Can you please let me know what is going on here?

I literally dont know where is the

"(Power of 2 +1) * (Power of 3+1) * (Power of 5+1)

Total factors = (3+1)∗(3+1)∗(1+1)"

coming from ?????

This is a general rule to calculate the total no of factors of a number from its prime factors.

If a number N has a, b and C as its prime factors such that

\(N=(a^p)*(b^q)*(c^r)\)

Then the total no of factors of N will be \((p+1)*(q+1)*(r+1)\)

This will include 1 and the number it self.
