8413

8413 is an integer in the decimal numeral system. It is a composite number known as a semiprime, since it can be expressed as the product of two primes: 47 and 179. This factorization implies that the positive divisors of 8413 are exactly 1, 47, 179, and 8413.

As a product of two distinct primes, 8413 is square-free and has four positive divisors. It is an odd number and congruent to 1 modulo 4. Its decimal digits sum to 16, giving a digital root of 7. In standard positional representations, 8413 is written as 8413 in base 10, its binary representation is 10000011011101, and its hexadecimal form is 0x20DD.

8413 does not have the properties of a prime or a perfect power, and it is not a palindrome in decimal. In number theory, semiprimes like 8413 are studied for their factorization characteristics and their distribution among the integers, as they lie between primes and higher-order composites in the hierarchy of integer factorization complexity. Because 8413 factors into two small primes, it serves as a simple example of a semiprime and can be used in educational contexts to illustrate basic divisor counting and base-conversion concepts.
