The Number Rarity Lab
How Rare Is Your Number?
Enter any number from 0 to 1,000,000 to uncover its mathematical traits, pattern rarity, and global percentile.
Transparent scoring. Exact counts. No sign-up required.
This number's digits add up to an uncommon total.
This number uses an uncommon count of distinct digits.
Divisible by the sum of its digits.
Why is 142,857 unusual? Only 50.1% of the 1,000,001 supported numbers receive an equal or higher rarity score. This number falls in the Standard tier. Scoring is grounded in the exact frequency of each detected trait — rarer traits carry more information and contribute more to the score.
