The **Fundamental Theorem of Arithmetic** states that:

**Every integer greater than 1** can be written uniquely (up to the order of the factors) as a product of prime numbers. 

In simpler terms:
- Any integer \( n > 1 \) is either a **prime number** itself or can be factored into a product of primes. 
- This factorization is unique, meaning that regardless of how you factor a number, the prime factors (and their powers) will always be the same, though the order of multiplication may vary.

### Example:
Consider the number 60.
- 60 can be factored as \( 60 = 2^2 \times 3 \times 5 \).
- No matter how you factor 60, you'll always end up with the prime factors 2, 3, and 5.

### Why is it important?
The Fundamental Theorem of Arithmetic is crucial because it ensures the **uniqueness of prime factorization**, which is the foundation for many areas of number theory, cryptography, and algebra.
