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 81 and 256, you can use prime factorization. Prime factorizing 81 gives you 3^4, and prime factorizing 256 gives you 2^8. The common factors between 81 and 256 are 1, 3, and 9. Therefore, the GCF of 81 and 256 is 9.
The GCF is 128.
The GCF is 1.
gcf(116, 256) = 4.
