Which is the greatest number in maths?

There is no greatest number in mathematics.

Why There's No Largest Number

The concept of a "greatest number" in mathematics is often misunderstood. Here's why it doesn't exist:

  • Numbers are infinite: According to mathematical principles, numbers continue infinitely. For every number you can think of, you can always add one (or any other number) to it and create a bigger number.
  • No End: As stated in the provided reference, "In mathematics... the largest number has no end." This fundamentally means there's no upper limit to numbers.

Understanding Infinity

While we can conceive of extremely large numbers (like a googol or a googolplex), these are still finite numbers. Infinity isn't a number in the traditional sense; it's a concept representing something without any limit. Therefore, you can't define a "largest" infinite number.

Examples

  • Let's say you think 1,000,000 is the biggest number. I can easily add 1 to it and get 1,000,001, which is bigger.
  • No matter how many zeros you add to a number, you can always add another zero to make it larger.

Smallest Number vs. Largest Number

The reference indicates that "1 is the smallest number" This is only partially true depending on the context. When we are talking about Natural numbers (positive whole numbers) 1 is the smallest. But if we consider integers (which include negative whole numbers), there is no smallest number as negative numbers extend infinitely in the negative direction.
