In this blog post, I’m sharing as many math facts about the number 2026 as I can find on my own or shared by others on Bluesky. I’m publishing the post before the year ends, but I will add additional number facts after the new year begins as well.
Countdown to 2026:
Here’s a countdown you can use right before midnight on New Year’s Eve:
Here’s another countdown I saw on Bluesky:
Here’s another nerdy & numerical New Year countdown I came across! This time, for the upcoming 2026. Enjoy using this for the upcoming year! :3 #Mathematics #MathSky #MathChat #MathsChat #NewYearCountdown #NewYear2026

If you have any problem seeing the 2026 video, here is a screenshot of its final frame.
Factors of 2026:
- 2026 is a composite number.
- Prime factorization: 2026 = 2 × 1013.
- 2026 has no exponents greater than 1 in its prime factorization, so √2026 cannot be simplified.
- The exponents in the prime factorization are 1 and 1. Adding one to each exponent and multiplying, we get (1 + 1)(1 + 1) = 2 × 2 = 4. Therefore, 2026 has exactly four factors.
- The factors of 2026 are outlined with their factor pair partners in the graphic below.
What Kind of Shape is 2026 in?
2026 can’t claim a shape of its own, but it does have a relationship with some other numbers that can.
2026 is one more cube than the sum of the cubes from 1 to 9.
1³ + 1³ + 2³ + 3³ + 4³ + 5³ + 6³ + 7³ + 8³ + 9³ = 2026.
2026 is the sum of three perfect squares in several different ways.
45² + 1² = 2026, so it’s shaped like this: 
(You can click on images to see them better. Each of the 2026 cells is numbered.)
2(23² + 22²) = 2026. Since it’s double the sum of consecutive squares, it’s also shaped like this:
Since 2026 = (2(22) + 1)² +1, it is also one more than the 22nd centered octagonal number.
2026 is also the sum of three triangular numbers in 31 different ways:
Changing from 2025 to 2026:
Happy New Year everyone!

Yes, 2026 is one more than 2025, or in the case of this video, 2026 is one more car than 2025.

And in a brilliant post on Bluesky, 2026 is one more billiard ball than 2025.
Some “Powerful” Facts About the Number 2026:
Since 2026 is the sum of an even number of consecutive numbers,
505 + 506 + 507 + 508 = 2026, we get this “powerful fact”:
508² – 507² + 506² – 505² = 2026.
45² + 1² = 2026, so
(3² + 6²)² + 1² = 2026.
2026 would be a palindrome in base 13 and in base 45:
11(13²)+12(13¹)+11(13º) = 2026.
1(45²) + 0(45¹) + 1(45°) = 2026.
2026 is in exactly two Pythagorean triples:
90-2024-2026, and
2026-1026168-1026170.
On October 24, 2026, we can celebrate the Pythagorean triple,
10-24-26.
I’ll finish off this topic with a “powerful” math joke about 2026:

2026 in Complex Numbers
2026 is the sum of two squares, 45² + 1², therefore it is the product of two complex numbers. If you are logged into Bluesky, you can see that complex product in the following post:
Here are two other complex number facts involving the number 2026:
2026 Games and Puzzles
Math=Love has mazes and other puzzles featuring the number 2026.
2026 is divisible by 2, but not by 4, so it is the magic sum of a magic square puzzle, specifically the one that uses the numbers from 499 to 514.
Happy 2026!
Here’s when 2026 starts around the world! It’s that time of year again, and we can play the 2026 NCTM Year Game in our January lessons. Use the digits in the year 2026 and the operations +, −, x, ÷, sqrt (square root), ^ (raise to a power), ! (factorial), along with grouping symbols to…

Peter Rowlet reports on Bluesky that the 2026 game works for the numbers 1 to 10 but doesn’t spoil your fun.
MathGames has also shared some 2026 fun facts and games.
Among other mathematical facts about the number 2026, Scientific American’s reprint of Spektrum der Wissenschaft’s Why 2026 Is a Mathematically Special Number informs us that the 8-magnetic-disk version of the mathematical game, Tower of Hanoi, will always take at least 2026 moves to solve.
More About the Number 2026:
0 + 12 × 34 × 5 – 6 – 7 + 8 – 9 = 2026. You can find another count-up equation on the MathGames blog.
2026 degrees is 1013π/90 radians.
If you are logged into Bluesky, you can see The Maths Bazaar’s post informing us that
2026 = 2¹¹ – 2 × 11,
2026 = √(2²²) – 22, and
that each of the following is a prime number:
2026 + 1,
2 + 0 × 26 + 1,
20 × 26 + 1,
202 × 6 + 1.
2026 = √(2²²) – 22 inspired me to make a graphic for it and some other equations I had already found:
Mathometry has some suggestions for math activities involving the number 2026.
From this Bluesky post and its link to OEIS, I learned that there are “2026 hyperforests spanning 10 unlabeled nodes without isolated vertices.”
