Fundamental Theorem of Arithmetic
In number theory, the fundamental theorem of arithmetic, also called the unique factorization theorem or the unique-prime-factorization theorem, states that every integer greater than 1 either is prime itself or is the product of prime numbers, and that, although the order of the primes in the second case is arbitrary, the primes themselves are not.

GCF and LCM
Finding the GCF and LCM of two or more numbers allows a user of mathematics to more quickly compute solutions. This sheet gives the prime factorization, so a student can begin to learn how to find common factors or common multiples.
