It's around 4,000 to 6,000. nobody has ever actually counted that high, so its unknown 0_o
1. being 5. any other number ending in a 5 is divisable by 5
The last two prime numbers before 30 are 29 and 23.
No. You can tell this by looking at the last number 5 goes evenly into numbers ending in 0 and 5. Five does not go evenly into 7.
There isn't one. Numbers don't stop. There doesn't exist a number so large that one can't be added to it.
The last prime number before 50 is 47.
the last even number before 900,000 is 899,998
There cannot be the last two prime numbers because there are an infinite number of them.
Mathematically, it isn't possible to have a "last number", as you could also multiply it by two or even by itself. There is a term used to describe the largest number, known as infinity. Which is based off of the word infinite - meaning never ending. I think that pretty accurately describes numbers.
Numbers don't stop because you can still multiply the last number; if you don't believe me count to the last number.
When the last digit is zero. All whole numbers of more than one digit and with a last digit of 0, 2, 4, 5, 6 or 8 are divisible by another number. Numbers ending with the other digits, 1, 3, 7 and 9, might be divisible by another number, and they might not.
The last whole number before 100,000 is 99,999
The truth is there is no last number. A number will always keep going on no matter what.
