WebMar 24, 2024 · There exist a variety of formulas for either producing the nth prime as a function of n or taking on only prime values. However, all such formulas require either extremely accurate knowledge of some unknown … WebStep 1: Check the units place of that number. If it ends with 0, 2, 4, 6 and 8, it is not a prime number. Note: “ Numbers ending with 0, 2, 4, 6 and 8 are never prime numbers. ”. Step 2: …
