The factors of 184 are:
1, 2, 4, 8, 23, 46, 92, 184
The factors of 207 are:
1, 3, 9, 23, 69, 207
The common factors are:
1, 23
The Greatest Common Factor:
GCF = 23
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 48, 72, and 96 is 24
13, 26, 39 are three numbers with a GCF of 13.
Oh, what a happy little math question! To find the greatest common factor of 90, 105, and 165, we first need to find the factors of each number. Then, we look for the largest number that divides evenly into all three. Let's paint a picture together and discover that the greatest common factor of 90, 105, and 165 is 15. Keep up the good work, there are no mistakes in math, just happy little numbers!
That presumes that math class is not part of the real world, which is debatable. Finding the greatest common factor can help reduce fractions. In a practical, non-academic setting, chefs and carpenters work with fractions and might have need of this skill.
You need to find work out the factors of both 45 and 105 separately, and then find which match both numbers. 45 - 1, 3, 5, 9, 15, 45 105 - 1, 3, 5, 7, 15, 21, 35, 105 The numbers that match both 45 and 105 are 1, 3, 5, and 15. 15 would therefore be called the Greatest Common Factor (GCF).
You need at least two numbers to find a GCF.
is 8
1,3,7,9,21,63 1,2,3,4,8,9,18,24,36,72 The factors in common are 1,3,9 The largest (greatest) common factor is 9
the greatest common factor of 28 and another number is 7 the second number is between 60 and 70 what is it show your work
8 = 1 * 8 24 = 3 * 8 GCF is 8.
To work out the greatest common factor, you need two numbers. In this case there is only one number so there is no GCF.
List the factors. 1,7 1,2,4,5,10,20 The only, and therefore the greatest common factor is 1.
1, 2, 4, 81, 2, 5, 10The GCF is 2.
There's no work to show. 24 is a factor of 48, so it has to be the GCF.
6 and 12 will work.
Two or more numbers are needed to work out their GCF
If you construct them correctly, factor trees always work to determine the prime factorization of a number. Once you compare the prime factorizations of two or more numbers, it is relatively easy to find the greatest common factor of them from there.
