you have to use long as the answer is too big and can't accommodate in an integer variable

import java.math.BigInteger; public class Factorials { public static void main(String[] args) { int number = 1; BigInteger factor = new BigInteger("1"); int i =1; for(number = 1; number <= 10; number++) { for(i = 1; i <= number; i++) factor = factor.multiply(BigInteger.valueOf(i)); System.out.println(factor); } }}

int is enough if you want 10x calculate factorial like 1*2*3... you must start each next iteration with factor=1 but you start with last factorial like 120*1*2*3... so for(number = 1; number <= 10; number++) { factor=1; // added for(i = 1; i <= number; i++) factor *=i; System.out.println(factor); }

Thank You Ver Much! restarting the iteration w/factor =1 solved it......

I adjusted the type to long but the math still doesnt come out right?... https://code.sololearn.com/cqVNrCMhqER6/?ref=app
