WebA prime number is the one which has exactly two factors, which means, it can be divided by only “1” and itself. But “1” is not a prime number. Example of Prime Number 3 is a prime number because 3 can be divided by only two number’s i.e. 1 and 3 itself. 3/1 = 3 3/3 = 1 In the same way, 2, 5, 7, 11, 13, 17 are prime numbers. Composite Numbers WebThe examples of composite numbers are 6, 14, 25, 30, 52, etc, such that: In all the above examples, we can see the composite numbers have more than two factors. There are a number of composite numbers we can list out of a set of natural numbers from 1 to 1000 or more. Let us see the list of composite numbers in the next section.

Let us find the lowest primitive root of 761: s = ϕ ( 761) = 760 = 2 3 × 5 × 19. the powers to test are: 760 / 2 = 380, 760 / 5 = 152 and 760 / 19 = 40 (just 3 instead of testing all of them) test 2: 2 380 ≡ 1 mod 761 oops. ata engineering testing
