List all the factors of 14 from least to greatest?

Answer 1

Short answer: {1,2,7,14}

Obviously 1*14 = 14, so 1 and 14 are two factors. 1 and the number itself is always two factors, no matter what number you have. You also know that 2*7 = 14. So now you have at least 2 and 7 as factors, right? 2 and 7 are both prime numbers, so now you know you won't find any other factors. This is because a Prime number cannot be factored into smaller numbers.
