Java: trying to calculate binomial coefficient with implementing big decimal. My code can calculate already, but not high numbers. i need BigDecimal [duplicate]

need help here to maybe convert long to BigDecimal or something. My solution to n=49, r=6 is 1 but is has to be 13983816.

need help here to maybe convert long to BigDecimal or something. My solution to

import java.math.BigDecimal;      public class BinomialCoefficient {        public static long factorial(int number) {          long factorial = 1;          for(int i = 1; i <= number; i++) {              factorial *= i;          }          return factorial;      }        public static void main(String[] args) {          int n = 49, r = 6;          long nChooser;                   nChooser = factorial(n)/(factorial(r)*factorial(n-r));                    //BigDecimal.valueOf(nChooser);                              System.out.println(nChooser);      }  }
