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 18 and 315 is: 9
The GCF of 216180 and 315 is 45
35 is the greatest common factor of 315 and 245.
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
