To find the Greatest Common Factor (GCF) of 78, 168, and 486, we first need to find the prime factorization of each number.
78 = 2 * 3 * 13 168 = 2^3 * 3 * 7 486 = 2 * 3^5
Next, we identify the common prime factors among the three numbers, which are 2 and 3. The GCF is the product of these common prime factors raised to the lowest power they appear in any of the numbers. Therefore, the GCF of 78, 168, and 486 is 2 * 3 = 6.

What is the GCF of 405 and 486?
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.
