The greatest common factor (GCF) of two numbers is the largest positive integer that divides both numbers without leaving a remainder. To find the GCF of 231 and 693, you can use prime factorization. The prime factorization of 231 is 3 x 7 x 11, and the prime factorization of 693 is 3 x 3 x 7 x 11. The common factors are 3, 7, and 11, so the GCF of 231 and 693 is 3 x 7 x 11, which equals 231.
