Euclid proved there are infinitely many primes c. 300 BCE using a one-line argument that still appears in every number-theory course.

§01What is

Understanding the 1000 Prime Numbers

The 1000 Prime Numbers computes Primes from 1 input: count. List of the first 1000 primes.

Mathematics shows up in every corner of daily life — budgeting, cooking, construction, engineering, even reading a bus schedule. A calculator like this lets you skip the scratch-paper step and move straight to the answer, without the arithmetic mistakes that creep in when the numbers get messy. The 1000 Prime Numbers sits in that toolkit — it list of the first 1000 primes. Enter your numbers above and the result updates instantly; every step of the math is shown in the Derivation panel so you can see exactly how the answer was reached.

Step-by-step walkthrough

Scenario

Apply the formula to a realistic set of inputs: Count = 25.

  1. 01Start by noting the input — Count: 25.
  2. 02Substitute these values into the formula: a.join(", ")
  3. 03Compute Primes: the calculator returns 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.
  4. 04Cross-check the answer by opening the Derivation panel above — every line of math is shown so you can follow the computation end-to-end.
