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.Since 305 is a single number, you could say that it shares all of its factors with itself. So the greatest factor of 305 is 305
The GCF is 5.
The factors of 55 are:1, 5, 11, 55The factors of 305 are:1, 5, 61, 305The common factors are:1, 5The Greatest Common Factor (GCF) is:5
The factors of 15 are:1, 3, 5, 15The factors of 305 are:1, 5, 61, 305The GCF is 5.
One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 26 are 1, 2, 13, and 26. The factors of 1220 are 1, 2, 4, 5, 10, 20, 61, 122, 244, 305, 610, and 1220. The common factors are 1 and 2. Therefore, the greatest common factor is 2. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 26 are 2 and 13. The prime factors of 1220 are 2, 2, 5, and 61. The prime factors in common are a single 2, so the greatest common factor is 2.
The factors of 15 are: 1, 3, 5, 15The factors of 305 are: 1, 5, 61, 305The common factors are: 1, 5The Greatest Common Factor (GCF) is: 5
The greatest common factor of 30 and 65 is 5.5 x 6 = 305 x 13 = 65
