New Algorithm to Generate Prime Numbers from 1 to …

WebTools. In mathematics, a semiprime is a natural number that is the product of exactly two prime numbers. The two primes in the product may equal each other, so the semiprimes include the squares of prime numbers. Because there are infinitely many prime numbers, there are also infinitely many semiprimes. Semiprimes are also called biprimes. WebJun 30, 2024 · As we know that all prime factors of a number are always less than or equal to square root of number i.e; sqrt (n). So we generate all prime numbers less than or equals to 10^8 and store them in an array. Now using this segmented sieve we check each number from a to b to have exactly n prime factors.
