Then there are up to 2 32 possible numbers, and the prime number theorem estimates there are about 193,635,000 primes below this. I already have collected the bits Remember that 32-bit instructions in 64-bit mode clear the upper 32 bits of the registers. Sure, we can double efficiency by eliminating even numbers (which, other then 2, will never be prime), but n²/2 is still O (n²). There are 203280221 prime numbers less than 2 ^ 32. However, this is I have a script that generates two random 32-bit floating point numbers a and b, and divides them to make an output c. There are numbers for which n is prime but 2 n -1 isn't (such as 11); however, if n is composite, 2 n -1 must also be composite. Here's a random prime with 30 digits. One can use the primes in the 32-bit map for test divides to determine whether a 64 GIMPS has free software available for Windows, Linux, FreeBSD, Mac OSX. Click get_app Download to save as csv file. This means that we can store 28 bits instead of 32 bits for each prime number. Our technique The current versions are FNV-1 and FNV-1a, which supply a means of creating non-zero FNV offset basis. 32b presents all 203280220 32-bit odd prime numbers from 3 to 4294967291.
