What is Coprime number?

In number theory, two integers a and b are said to be relatively prime, mutually prime, or coprime (also written co-prime) if the only positive integer (factor) that divides both of them is 1. … A set of integers can also be called coprime if its elements share no common positive factor except 1.

How do you find a prime number greater than 100?

One can check that a number smaller than 100 is a prime just by checking that it is not divisible by 2, 3, 5, 7. This is because the next prime after 7 is 11, whose square is greater than 100 (hence the test holds if one replaces 100 by 120, note also that checking the divisibility by 9 is useless since 3 divides 9).
