As it was hard to miss, another calendar year began yesterday. If you look at its number alone, it does not promise to be extraordinary.

2022 (two thousand twenty-two) is an even four-digits composite number following 2021 and preceding 2023. In scientific notation, it is written as 2.022 × 103. The sum of its digits is 6. It has a total of 3 prime factors and 8 positive divisors. There are 672 positive integers (up to 2022) that are relatively prime to 2022.
