Problem 3: Factoring 3a. The function is prime (already defined) tests if a number is prime. Use it to test if the following integers are prime -??. 1 . 2017 -3a.2. 2015 -3a.3. 5089499053 158977852651592594959255499618560261658305128152749732980638928693867617555084993160281949064053399342129943623386301078583622070862781989642880265570519636898574116 9061589392187723374511476815445516292269023831265631925174400849066851 3b. Does 991 divide the number n from 3a.4? (Hint: a%b computes the remainder of a divided by b. One can test if b divides a by testing if a%bs equal to ) 3c. Write a function hsfactor(N) that takes as input a positive integer N and then tries to factor it the high-school way by going through all integers i
