1,2,3,5,7,11,13,17,19,23,29,31.... A prime number has exactly two factors. 2 is prime (its factors are 1 and 2) 3 is prime (its factors are 1 and 3) 5 is prime (its factors are 1 and 5) 1 is not prime (its only factor is 1, this is 1 factor, not 2) 4 is not prime (it has 3 factors: 1, 2, and 4) 6 is not prime (it has 4 factors: 1, 2, 3, and 6)
1-10 AD had the years 2, 3, 5, and 7, which were prime numbers.
Prime numbers from 1 to 12: 2, 3, 5, 7, 11Composite numbers from 1 to 12: 4, 6, 8, 9. 10. 12
1 is neither a prime or composite because it has one factor. 2 is prime because it's only factors are 1 and itself. 4 is composite because it has 3 factors: 1, 2, and itself.
No. A prime number is a number that can only be divided by itself and 1. The first prime number is 2 - which is also the only even prime number. The prime numbers from 1 - 20 are: 2 and 3 and 5 and 7 and 11 and 13 and 17 and 19
The prime numbers from 1 to 4 are 2 and 3.
If the two prime numbers are different: You get the two prime numbers, plus 1, plus the product. For example, if you multiply 2 x 3 = 6, the factors of 6 are 2, 3, 1, and 6. If the two prime numbers are the same: You get the prime number, 1, and the product. For example 2 x 2 = 4. The factors of 4 are 2, 1, 4.
No they are not prime numbers because 4 is composite.
Its factors are: 1 2 4 19 38 and 76 Prime numbers: 2 and 19 Composite numbers: 4 38 and 76 Note: 1 is neither a prime or composite number
There are 4 prime numbers, 2, 3, 5 and 7.

4
4: 2, 3, 5 and 7. 1 is not a prime.
Prime numbers before 10 are 2 3 5 7 So 4
1-10 AD had the years 2, 3, 5, and 7, which were prime numbers.
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. 4 and 6 are composite, 5 is prime.
4 = 4, and 4 = 2 x 2, so either a single prime number to the power 4-1 (23, 33, etc.), or two different prime numbers, each to the power 2-1, for example, 2x3, 2x5, 3x5, etc.
