Calculate Prime Numbers Before 250: The number 250 is not a prime number because it is possible to express it as a product of prime factors. In other words, 250 can be divided by 1, by itself and at least by 2 and 5. So, 250 is a 'composite number'. 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.
