WebOct 7, 2012 · This sieve can be 'pre-calced' for a certain number of factors. Because lcm (2, 3, 5, 7) == 210, the pattern of numbers eliminated by these factors will repeat every 210 numbers, and only 48 remain. In that way, you can eliminate 77% of all numbers from trial division, instead of the 50% by taking only odds. – primo. WebDec 29, 2024 · Prime factorization is when we break a number down into factors that are only prime numbers. If we look at the above example with 20, the factors are 1, 2, 4, 5, 10, 20. The best place to start is to find at least one initial factor that is prime. Since 5 is prime, we can start with 4 * 5. Notice that 4 is not prime, so we break 4 down into 2 * 2.
