## Fun Fact related to the Number 321:

In the realm of mathematics, 321 is an interesting number because it is a palindromic number. This means that it reads the same backward as forward, much like words like “radar” or “level.” Palindromic numbers often have a special fascination for people due to their symmetry.

Another fun fact is that 321 is a composite number, meaning it has factors other than 1 and itself. In this case, 321 can be expressed as the product of 3 and 107 (3 x 107), making it composite. Composite numbers have divisors other than 1 and the number itself, in contrast to prime numbers, which have only two divisors: 1 and the number itself.
