- elementary number theory - Sum of all the factors of $33333333 . . .
Factors of $33333333=3\times11111111=3\times11\times1010101=3\times11\times101\times10001$ And now I was lost (just before the last step) as I couldn't confirm if 10001 is prime or not A solution I got: $10001=11025-1024=105^2-32^2=137\times73$ which are primes
- $0. 333333$ - a recurring or non-terminating decimal?
1) A terminating decimal representation means a number can be represented by a finite string of digits in base $10$ notation, e g $0 5$, $0 25$, $0 8$, $2 4$
- Finding sum of factors of a number using prime factorization
Given a number, there is an algorithm described here to find it's sum and number of factors For example, let us take the number $1225$ : It's factors are $1, 5, 7, 25, 35, 49, 175, 245, 1225 $ and

- sequences and series - Is 1 divided by 3 equal to 0. 333 . . .
I have been taught that $\frac{1}{3}$ is 0 333 However, I believe that this is not true, as 1 3 cannot actually be represented in base ten; even if you had infinite threes, as 0 333 is supposed to represent, it would not be exactly equal to 1 3, as 10 is not divisible by 3

- Graph with degree sequence (3,3,3,3,3,3) - Mathematics Stack Exchange
Does there exist a graph with degree sequence (3,3,3,3,3,3)? I am pretty such graph does not exist since I have tried to draw one without success, but is there a way to prove it?
