Another thing thats significant about 7 is that it's the only single digit number to have 2 syllables, which makes it good for use in writing. Single syllable words often don't sound very good. Think about Durin looking into the Mirrormere. "And above his head he saw a crown of six stars appear" just doesnt sound as nice as "and above his head he saw a crown of seven stars appear."
a negative number cannot be a prime number because it will always have atleast three factors, 1, itself, and -1 and prime numbers can only have 2 factors
7 is evil, 8 was just a tool, and 9? Well, let's not talk about 9. Why? Because 7 8 9
7 ate 9😂what an evil thing to do
Interesting fact. Never knew this relationship between 7 and 8. Does it have any benefits or short cuts with other equations?
Fantastic video 👏✌️
This can be extended from cubes to other powers: If there's a prime p such that p=k^n-1, then k must be 2.
...and then Mersenne chimes in...
Interesting! Thanks!
Keep it up
Cool bro
You're right!
Pretty cool

Because 7 8 9
oh em gee that was sew inkeresteeing
"what's special about 7 and 8"
me, an intellectual: because 7 8 9 *shitty seinfeld laugh track*
Negative numbers can't be prime? Because if they could then -2 is prime and -1 is cubic...
yeah that does fit the equation, good find! but does that mean the proof was incorrect?
Good point! Part of the definition of a prime number, however, is that it's greater than 1.
@@BHNmath OK, thanks for correcting me
If it’s prime it has 2 factors. -2 has 4 factors
-2, -1, 1, 2
