First 70 Prime Numbers

The first 70 prime numbers. Primes are divisible only by 1 and themselves — they are the building blocks of all integers.

2 is the only even prime — every other even number divides by 2. The widest gap between consecutive neighbors in this list is 14: primes wander further apart as numbers grow, yet never run out — Euclid proved the supply is endless. The list stays tight as well: all 70 of these primes fit inside the range 2 through 349, where they make up about 20.1% of all integers — prime density thins slowly as numbers grow.
