19×67

19×67 denotes the product of the integers 19 and 67. Both numbers are prime, so their product is a semiprime, a composite number with exactly two prime factors. The calculation is straightforward: 19×67 = (20−1)×67 = 1340−67 = 1273.

The prime factorization of the result is 1273 = 19×67, confirming that the product has exactly two prime factors (counting multiplicity). The number 1273 is odd and not divisible by 2, 3, or 5; its divisors come from the original prime factors.

In mathematical contexts, 19×67 is often used as a simple example to illustrate basic multiplication of primes and the concept of semiprimes. It can serve as an instructional case for practicing factorization, prime numbers, and the behavior of products of primes. While small in value, such semiprimes highlight how composite numbers can be formed from prime components and how factorization reveals their structure.
