135 = 33 * 5
315 = 5 * 43
It is 5 because 5 is in both rows.
What about 15? Is it the greater common factor?
The GCF of 18 and 315 is: 9
The greatest common factor of 315 and 660 is 15.
It is: 3
The GCF is 21.
The GCF is: 45
The greatest common factor of 315 , 525 = 105
The answer is 45 135=3x3x3x5 315=3x3x5x7 each number has at least 2 3s and one 5 3x3x5=45 Your welcome
The Greatest Common Factor (GCF) of 84 and 315 is: 21
The Greatest Common Factor of 5, 315, 2: 1
Since 9 is a factor of 315, it is automatically the GCF.
The GCF of 315 and 450 is 45.
The GCF of 216180 and 315 is 45
35 is the greatest common factor of 315 and 245.
The GCF of 18 and 315 is: 9
The GCF of 56 and 315 is 7.
Since 315 is a factor of 1575, it is automatically the GCF of this problem.
GCF(315, 1000) = 5
