About the first 1,000 prime numbers

This page lists the first 1,000 prime numbers and lets you look up the nth prime by index. A prime number is a whole number greater than 1 that is divisible only by 1 and itself. You enter an index from 1 to 1000 (e.g. 223) and see the corresponding prime (e.g. 1409) immediately. The table below shows all 1,000 primes in order so you can scroll and browse. The list is generated in your browser using a sieve-like approach—no server or sign-up required. The tool is mobile-friendly and responsive.

Prime numbers are the building blocks of number theory and are used in cryptography (e.g. RSA), hashing, and many algorithms. The first prime is 2 (the only even prime); then 3, 5, 7, 11, and so on. This calculator helps students check homework, teachers prepare examples, and anyone explore the distribution of primes. The prime number theorem says the nth prime is roughly n·ln(n); for n = 1000, that’s about 6,900—the actual 1000th prime is 7919.

Use the index input to jump to a specific prime, or scroll the table to see the full list. For checking whether a single number is prime, use the prime number calculator. For breaking a number into prime factors, use the prime factorization calculator. This page is focused on listing and looking up the first 1,000 primes.

The list is generated once when the page loads and is kept in memory, so nth-prime lookups are instant. The table is scrollable and works on phones and tablets; on very small screens the grid shows two columns per row for easier tapping. The tool is free, works offline after load, and does not send your input anywhere.
