Not really, knowing that any number ending in a 0,2,4,6, or 8 will be even means that given the task of determining even or odd, my brain ignores anything before the final digit.
I have a hard time wrapping my head around the fact that you can have prime numbers that are larger than 1000. Like 104,729 is prime, it feels wrong that a number so big doesn’t have at least one clean factor in it.
Humans have very bad intuitions about large numbers. It makes sense if you think about evolution and human history. There was no need in early human history to be able to reason “I should be able to split this group of sheep up evently, there’s about 7 million of them,” but you better believe that people needed to say “there are 4 tigers following us, let’s split up into two groups”. Etc.
Your observation makes logical sense from a purely visual and pattern-recognition standpoint. The digit “7” repeated multiple times strongly signals an odd pattern cognitively, thus creating an intuitive expectation for oddness. However, numerical parity (evenness or oddness) is strictly determined by the final digit—in this case, “2,” which is unequivocally even—regardless of the preceding repetitive digits. Therefore, despite its deceptive appearance, the number 777,777,772 must logically remain even, irrespective of the discomfort caused by this visual contradiction.
I mean the average human being can’t *meaningfully* comprehend much beyond numbers in the hundreds or low thousands, so I’d reckon any number over 9,000 is basically honorarily odd, and like….I would be correct with a 50% accuracy rate if you think about it.
It just feels that way because as you read the number from left to right, you see a bunch of odd digits, and have already associated the number with being odd by the time you read the last digit.

Wait till OP finds out about 222,222,227 – Best. Day. Ever.
I don’t believe you, gimme a second.. let me count on my fingers

It’s so easy to check though. You just count the number of odd digits… 8 sevens, and 8 is an even number so therefore 777,777,772 must be even!

It’s just oddly difficult to divide in your mind
I like the number 51 because it’s just feels like a prime number even though it isn’t.
All those odd sevens cancel out the two’s evenness.

Feels even more like a crime that it’s not divisible by 3
Not to me.
Maybe you have an odd idea of oddness.
That it isn’t divisible by 7 into a whole number feels icky too.
Would it be any worse if you added another 7 before the 2?

No it doesn’t. The odd/even rule is locked by the last number so it’s easy to ignore everything but the last number.
dude fr it looks so odd, all those 7s just scream “yeah i’m odd” and then boom… that lil 2 at the end ruins everything
And that 12,345,678,910,987,654,321 has no other factors other than 1 and itself

You can put yourself through enough pain
But people won’t know unless you make
Enough noise
i don’t get it ngl. you can’t divide that number by two?
51 is not prime. I hate that. It just looks prime to me.
