The document contains examples of finding the prime factorization of various numbers and calculating the greatest common factor (GCF) of other numbers. It lists the numbers 22, 31, 25, and 29 and whether they are prime or composite. It then provides examples of finding the prime factorization of 84, 60, -154, 18, and -45. The final examples show calculating the GCF of 12 and 18 and of fractional numbers.
