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.
The Greatest Common Factor (GCF) is: 13
39 and 93's highest common factor is three.
39 and 45's highest common factor is three.
It is: 13
The GCF is 13.
The highest common factor of the numbers 39, 91 and 169 is 13.
The greatest or highest common factor is the highest number that divides exactly into two or more numbers. 39: 1, 3, 13, 39 87: 1, 3, 29, 87 The greatest common factor for 39 and 87 is 3.
The Greatest Common Factor (GCF) is: 13
The Greatest Common Factor (GCF) is: 1
Three.
1
It is 3
1
Since 13 is a factor of 39, it is automatically the GCF of this problem.
39 and 93's highest common factor is three.
39 and 45's highest common factor is three.
It is: 13
