247105

247105 is a natural number that lies between 247104 and 247106. In decimal notation, it ends with the digit 5, which means it is divisible by 5. The prime factorization begins with 5 multiplied by 49,421, so 247,105 = 5 × 49,421. The sum of its digits is 19, so the number is not divisible by 3, and it is not even since it is odd. It is not a palindrome in base 10. Aside from these basic divisibility facts, there are no widely known special mathematical properties associated with this specific six-digit integer.

In arithmetic and number theory, six-digit integers like 247105 commonly appear in examples and test cases to illustrate concepts such as divisibility, modular arithmetic, and factorization. As a representative member of the range, it can be used to demonstrate how endings influence divisibility rules or how to perform simple factorization steps.

In an astronomical context, numbers of this form are often used as sequential designations for minor planets or other small Solar System bodies after discovery and confirmation. However, without a specific provisional designation or naming reference, 247105 itself does not imply a particular object.
