It is a composite number because it has more than two factors
711 is a composite number. This is because composite numbers are any number that has more than two factors (one and itself). Therefore, since there are many factors of 711 besides one and itself such as 3, 9, and 79, that makes it a composite number.
A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 711 is composite.
137 and 127 are the only two prime numbers in the list.
From the sum of digits method, 711 is a multiple of 9, so no it is not prime.
1, 3, 9, 79, 237, 711 3 and 79 are prime.
neither prime or composite
It is prime
It would be impossible to list them all, since numbers go on forever, but here are some of them: 2 - Prime 3 - Prime 4 - Composite 5 - Prime 6 - Composite 7 - Prime 8 - Composite 9 - Composite 10 - Composite 11 - Prime 12 - Composite 13 - Prime 14 - Composite 15 - Composite 16 - Composite 17 - Prime 18 - Composite 19 - Prime 20 - Composite 21 - Composite 22 - Composite 23 - Prime 24 - Composite 25 - Composite 26 - Composite 27 - Composite 28 - Composite 29 - Prime 30 - Composite 31 - Prime 32 - Composite 33 - Composite 34 - Composite 35 - Composite 36 - Composite 37 - Prime 38 - Composite 39 - Composite 40 - Composite 41 - Prime 42 - Composite 43 - Prime 44 - Composite 45 - Composite 46 - Composite 47 - Prime 48 - Composite 49 - Composite 50 - Composite
Because a prime number is a number that can only be divided on itself and 1, and 711 can be divided on, for instance, 3.
4, composite. 67, prime.
