Number of divisors d(n): 2 Complete list of divisors: 1 2147483647 Sum of all divisors σ(n): 2147483648 Sum of proper divisors (its aliquot sum) s(n): 1 2147483647 is a deficient number, because the sum of its proper divisors (1) is less than itself. Its deficiency is 2147...
Consider just one essential example: "Every positive number has a unique factorization into primes". This would not be true if "1" was considered prime since you could add any number of "1" factors to (other) primes and obtain a product with the same value. Even "1" has a unique fa...
* The prime number theorem says that the proportion of primes less than x is asymptotic to 1/ln x (in other words, as x gets very large, the likelihood that a number less than x is prime is inversely proportional to the number of digits in x). ...
all of which are prime. Numbers in this sequence grow in size rapidly. Thus, 711 + 7 + 11 = 1,977,326,761, which is harder to check for primality by use of a pocket calculator than its predecessors. Of course, it is easily handled by a modern computer. Even this is not necessary...

Observe that all other primes (infinity of them) are odd. Before the advent of digital computers, i.e., before 1940’s, loge (natural logarithm), and log10 (common logarithm) were the ones most used and most dominant. During the digital computer age, log2 has gained at least the same...
Subash, a user of my math site (Interactive Mathematics) asked recently whether 0 is a Natural Number or not. My reply: Normally I have always taken the Natural Numbers to start at 1 and not to include zero. I used to get my students to remember the difference between Natural Numbers an...
