@sanyamsri2001 hey sanyam there is a method exist you can compute the factorial of large no
refer this discuss for algorithm

Broken CAlculator Explain the method and appoach to Problem

@sattyrajpoot39 hey satyam Create an array ‘res[ ]’ of MAX size where MAX is number of maximum digits in output. Initialize value stored in ‘res[ ]’ as 1 and initialize ‘res_size’ (size of ‘res[ ]’) as 1. Do following for all numbers from x = 2 to n…… a) Multiply x with res[ ] and update res[ ] and res_size to store the multiplication result. multiply(res[ ], x) Initialize carry as 0. Do following for i = 0 to res_size – 1 …… a) Find value of res[i] * x + carry. Let this value be prod. …
