Primality check
WebMay 3, 2024 · a) Take the square root of a number. b) Round of the square root to the immediately lower integer. Call this 'z'. For example if you have to check for 181, its square root will be 13.xx. Hence, the value of z, in this case will be 13. c) Check for the divisibility of the number N by all prime numbers below z. WebSequentially test a sequence of (big) numbers for primality, and find the total time taken: Table[PrimeQ[2^Prime[n] - 1], {n, 500}] // Counts // AbsoluteTiming Doing the same thing in parallel takes considerably less time:
