The greatest common factor (GCF) of two numbers is the largest number that divides both numbers without leaving a remainder. To find the GCF of 405 and 486, we can use the prime factorization method. First, we find the prime factors of both numbers: 405 = 3 x 3 x 3 x 3 x 5 and 486 = 2 x 3 x 3 x 3 x 3 x 3. Then, we identify the common prime factors, which are 3 x 3 x 3 = 27. Therefore, the GCF of 405 and 486 is 27.
