Factors of 27: 1, 3, 9, 27
Factors of 86: 1, 2, 43, 86
GCF (27, 86) = 1
No. The Greatest Common Factor (GCF) is the greatest factor that is in common with the numbers you are given.
To have a common factor, two or more numbers must be factored and the largest factor that occurs in each number is the greatest common factor.
That's known as the Greatest Common Factor, or GCF.
7
The GCF is 8.
That's a misrepresentation of the term "greatest common factor," or GCF, which is the largest number that will divide evenly with no remainder into all the members of a set of two or more given numbers.
As the numbers are all prime, the only factors each of them has are 1 and the number itself. Therefore the greatest, and only, common factor of two of more prime numbers is 1.
121: 11-11 132: 2-2-3-11 Great common factor: 11 Method(s) used: # (used) The method to find the greatest common factor of numbers is to find the prime factorizations of each one, select all matching prime factors, and then multiply. # An alternative method is to find all of the factors of each, and then select the greatest number that appears in each list. # The final method only applies to some numbers; if one of the number is a factor of the other, then that number is the greatest common factor. This is because all numbers are factors of themselves, and that is their greatest factor. If it is also a factor of the other number, then it is definitely the greatest common factor.
The GCF of a set of numbers is a positive integer which divides each of the numbers evenly.
2 and 3
The greatest common factor (GCF) of two (or more) numbers is the greatest factor that divides two numbers. To find the GCF you must work out and list the prime factors of each of the numbers. You will see that the numbers have prime factors in common. Multiply those factors the numbers have in common together and this gives you the GCF for the numbers. eg Number A = 18, Prime factors = 2*3*3 Number B = 24, Prime factors = 2*2*2*3 The Prime factors that A and B have in common are 2 and 3 Multiply them together = 6 6= the GCF of 18 and 24
