## Greatest Common Factor

Summary

The content provides an in-depth exploration of the concept of the greatest common factor (GCF), detailing methods to calculate it for pairs of integers, with a focus on using prime factorization for larger numbers.

- GCF, also known as the greatest common divisor, is a fundamental mathematical concept used to identify the largest factor common to two integers.
- The traditional method of listing all factors to find the GCF is impractical for large numbers, necessitating the use of prime factorization.
- Prime factorization involves breaking down each number into its prime factors and identifying the highest power of common primes to calculate the GCF.
- Examples provided illustrate how to apply prime factorization to find the GCF of large numbers efficiently.
- The significance of finding the GCF extends beyond the calculation itself, as it is pivotal in determining the least common multiple (LCM), which is discussed in subsequent content.
