5×1019

5×1019 denotes the product of the integers 5 and 1019. In decimal form, this product equals 5095.

The prime factorization of 5095 is 5095 = 5 × 1019, where 1019 is a prime number. Because it is the product of two primes, 5095 is a semiprime. It has exactly four divisors: 1, 5, 1019, and 5095. The number is odd and ends with 5, so it is divisible by 5 but not by 2 or 4. The sum of its digits is 19, so it is not divisible by 3 or 9.

In mathematical contexts, semiprimes like 5095 are used to illustrate basic factorization properties and divisor counting. They also appear in discussions of primality and composite structure. In applied areas such as cryptography, larger semiprimes composed of two large primes are of interest, though 5095 itself has no practical cryptographic application due to its small size.

Summary: 5×1019 equals 5095, with prime factorization 5 × 1019. It is a small semiprime, having exactly four divisors, and serves as a basic example in elementary number theory.
