It is: 13
To find the GCF of 13 and 39, you can list the factors of each number. The factors of 13 are 1, 13. The factors of 39 are 1, 3, 13, 39. 13 is the GCF of 13 and 39. 3 is a prime number has only two factors: 1 and 13. 13 will divide into 39 three times. Since 13 is a prime number that will divide into 39, it has to be the GCF of 13 and 39.
The factors of 39 are:1, 3, 13, 39The factors of 61 are:1, 61The Greatest Common Factor (GCF) is:1
The factors of 39 are: 1, 3, 13, 39.The factors of 87 are: 1, 3, 29, 87.The common factors are: 1, 3.The Greatest Common Factor (GCF) is: 3
To find the greatest common factor (GCF) of 57, 39, and 15, we need to first find the factors of each number. The factors of 57 are 1, 3, 19, and 57. The factors of 39 are 1, 3, 13, and 39. The factors of 15 are 1, 3, 5, and 15. The common factor among all three numbers is 3, making it the greatest common factor.
There cannot be a greatest common factor (GCF) of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.
To find the GCF of 13 and 39, you can list the factors of each number. The factors of 13 are 1, 13. The factors of 39 are 1, 3, 13, 39. 13 is the GCF of 13 and 39. 3 is a prime number has only two factors: 1 and 13. 13 will divide into 39 three times. Since 13 is a prime number that will divide into 39, it has to be the GCF of 13 and 39.
The greatest common factor (GCF) of 39 and 104 is 13. To find the GCF, you can list the factors of each number and identify the largest number that divides both 39 and 104 without leaving a remainder. In this case, the factors of 39 are 1, 3, 13, and 39, while the factors of 104 are 1, 2, 4, 8, 13, 26, 52, and 104. The largest number that appears in both lists is 13, making it the GCF of 39 and 104.
