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.
The GCF is 26.
The GCF is 56.
The GCF is 6.
The GCF of 42, 60, 78 is 6.
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.
The GCF is 6.
The GCF is 1.
The GCF is 3.
The GCF is 18.
The GCF is 6.
The GCF is 6.
The GCF is 12.
The GCF is 14.
The GCF is 4.
The GCF/HCF of 486 and 405 is 81.
The GCF is 14.
The GCF of 40 and 168 is 8.
