Is 1 a Prime Number? (Why isn't 1 Prime?)
Is 1 prime? Is 1 a prime number? 1 is not a prime number and I go over that and the reason why in this video. 1 is not prime, nor is 1 composite, if you're wondering "Why isn't 1 prime?" we will go over that in this video. And I hope you find it helpful. 1 is not prime because of the prime number definition, thus it does not need to be proven, but we can explain why it is left out as a prime by definition.
I hope you find this video helpful, and be sure to ask any questions down in the comments!
