The HCF of the given two numbers is 17
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 170 and 255 is 85
The greatest common factor of 85 and 255 is 85.
5
The GCF is: 1
The GCF of 255 and 256 is 1.
The largest number that goes into 150, 160, and 255 is 5.
The largest number that goes into 150, 160, and 255 is 5.
You need at least two numbers to find something in common.
68 = 2 * 2 * 17 255 = 3 * 5 * 17 So it is 17.
You need at least two numbers to find a GCF.
Common factors are factors that are common to two or more numbers. For example, 7 is a factor of 14, 49, and 35, therefore it is a common factor of those three numbers. 2, 4, and 17 are all factors of 136, and 3, 5, and 17 are all factors of 255, so 17 is a common factor of 136 and 255.
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 36, 54, and 81 is 9
