### How does BigInteger modPow work?

BigInteger modPow() Method in Java modPow() method returns a BigInteger whose value is (thisexponent mod m ). If exponent == 1, the returned value is (this mod m) and if exponent < 0, the returned value is the modular multiplicative inverse of (this-exponent). The method throws an ArithmeticException if m <= 0.

How do you solve 5 factorials?
