So I we know some x = 2^5 * 5^15 * 21^5 * 119 , Here we even know the prime factors

Then,

Is there any program in c language (or) any other easily understood computer programing language (so that I could convert into a c program using the same logic , since I know only c language programing) , (or) any easy algorithm to form

divisors at very fast speeds (because I require to form divisors for very large numbers) .

If any one have the code please give me , or any step wise explained algorithm is also sufficient.

Here I can formulate an algorithm by observing the factors of the number (i.e using the arrangement of factors in ascending or descending order), but I think ,this method is too slow to form the divisors for very very large numbers having a lot and lot of divisors in it.
