Example text

Therefore G is not the same as any one of the numbers A, B, and C, and by hypothesis it is prime. Therefore, the prime numbers A, B, C, and G have been found, which are more than the assigned multitude of A, B, and C. Therefore, prime numbers are more than any assigned multitude of prime numbers. There is little between this argument and Euclid’s proof in modern form on p. 8. Euclid did not have our modern notion of infinity, so he proved that there are more primes than any prescribed number. He also often stated proofs using examples (in this case, what he really proves is that there are more than three primes), but it is clear he understood the general case.

Take the least number DE measured by A, B, and C. Add the unit DF to DE. Then EF is either prime or not. First, let it be prime. Then the prime numbers A, B, C, and EF have been found, which are more than A, B, and C. Next, let EF not be prime. Therefore, it is measured by some prime number. Let it be measured by the prime number G. I say that G is not the same as any of the numbers A, B, and C. 40 1 A Brief History of Prime If possible, let it be so. Now A, B, and C measure DE, and therefore G also measures DE.

10 follows a survey paper of Dudley [46]. 9) was first proved by Tchebychef [151, Tome I, pp. 49–70, 63]. He also proved that for any e > 15 , there is a prime between x and (1 + e)x for x sufficiently large. 525 , x] for x sufficiently large. 7 is due to Mills [107]. 9 from a paper of Dressler [45]. 3 is taken from his Web site. A recent account of the GIMPS record-breaking prime is in Ziegler’s short article [167]. 16 appeared first in his paper [168]; a more accessible proof may be found in a short paper by Roitman [132].
