Hey @gupta.sonal2010 refer this you will be able to get the formula then
Formula
In general, if you have the prime factorization of the number n, then to calculate the sum of its divisors, you take each different prime factor and add together all its powers up to the one that appears in the prime factorization, and then multiply all these sums together!
Though if you still have anymore doubts left i am attaching an editorial for you so that you can get a clear idea of how sum of divisor can be calculate using GP
