The highest common factor of 25 and 39 is one as:
39 = 1 x 25 + 14
25 = 1 x 14 + 11
14 = 1 x 11 + 3
11 = 3 x 3 + 2
3 = 1 x 2 +1
2 = 2 x 1 + 0
and the last non-zero remainder is 1
The Greatest Common Factor (GCF) is: 1
The Greatest Common Factor (GCF) 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.
1
Three.
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.
The GCF is 13.
The GCF is 39.
