List all of the prime numbers less than 20 in numerical order
Answers
a prime number is a number only divisible by itself and 1 (this excludes decimals and fractions)
surprise, 1 is not prime because it must be divisible by itself and 1 and the factors of 1 are 1 and 1 so 1 is not prime
2 is prime because it is the first even counting number and since all even numbers after 2 are divisble by 2 you can cross out all odd numbers after 2 3 is prime because it is the first odd counting number that satisfies the condition 4 is not because it is even 5 is prime 6 is not because it is even 7 is prime 8 is not because it is even 9 is not 10 is not because it is even 11 is prime 12 is not because it is even 13 is prime 14 is not because it is even 15 is not 16 is not because it is even 17 is prime 18 is not because it is even 19 is prime 20 is not because it is even
so the numbers are 2,3,5,7,11,13,17,19
19, 17, 13, 11, 7, 5, 3, 2
