100 is the greatest common factor between 300 and 400
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 200, 250, and 400 is 50
A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 400 are 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, and 400. The factors of 500 are 1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, and 500. The common factors are 1, 2, 4, 5, 10, 20, 25, 50, and 100. Therefore, the greatest common factor is 100.
The greatest common factor (GCF) of 300 and 400 is 100. To find the GCF, you can list the factors of each number: 300 (1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300) and 400 (1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400). The largest number that appears in both lists is 100, making it the greatest common factor.
24 is not the greatest common factor of any single number. Common factors are the factors that two or more numbers have in common. The greatest common factor is the largest factor that two or more numbers have in common. There cannot be any common factors or a greatest common factor of a single number. There must be at least two number for common factors and a greatest common factor. Example: The greatest common factor of 24 and 48 is 24. The greatest common factor of 60 and 144 is 24. The greatest common factor of 240 and 264 is 24.
