568 divides evenly by these numbers: 1 2 4 8 71 142 284 and 568.
No, it is not. If you divide by 7 you get 71, so 497 cannot be a prime number.
No it is not, you can test this by trying to divide 781 by all prime numbers (p) where p^2<=781. note that 11 divides 781 evenly, with a remainder of 71. 11 is prime, and the existing factors of 71 can be tested using the same method, p^2<=71. noting that 9^2>71, we know if 71 is not prime, a prime number less than 9 must divide it. and since 2, 3, 5, and 7 do not divide 71 that is also prime Thus 781 is not prime, and the factors of 781 are 11 and 71.
no you can divide it by 71 and 2 and both of those are prime

yes it can, you must long divide, so the answer is 71
