In simple words, a **Prime Number** is a whole number greater than 1 that cannot be made by multiplying other whole numbers. It has exactly two factors: 1 and itself. For example, 7 is a prime number because only 1 × 7 = 7. However, 6 is not a prime number (it's a composite number) because 2 × 3 = 6.

In the world of technology, they are used in **Cryptography** to secure your online bank transactions and private messages. Programmers often use them in algorithms, and students need them for simplifying fractions or finding the Lowest Common Multiple (LCM).
By using the tool on expertsjava.com, you save time and avoid the common mistakes that happen during manual long division. Whether it's for a school assignment or a complex coding project, we've got you covered.
For quick reference, here are the first few prime numbers that our tool on expertsjava.com identifies:
Is 1 a prime number?
