To find the greatest common factor (GCF) of 180, 450, and 420, we first need to find the prime factorization of each number. The prime factorization of 180 is 2^2 x 3^2 x 5, the prime factorization of 450 is 2 x 3^2 x 5^2, and the prime factorization of 420 is 2^2 x 3 x 5 x 7. The GCF is the product of the common prime factors raised to the lowest power, which in this case is 2^2 x 3 = 12. Therefore, the greatest common factor of 180, 450, and 420 is 12.
