Yes - 315/15 = 21.
The GCF is 15.
The greatest common factor of 315 and 660 is 15.
The GCF of 60 and 315 is 15.The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60The factors of 315 are: 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315The common factors are: 1, 3, 5, 15The Greatest Common Factor (GCF) is: 15
Since 315 is a factor of 3150, it is automatically the GCF.
The GCF is 15.
135 = 33 * 5 315 = 5 * 43 It is 5 because 5 is in both rows. What about 15? Is it the greater common factor?
1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
1, 3, 5, 9, 15, 45
90 = 2x3x3x5210 = 2x3x5x7315 = 3x3x5x7GCF = 3x5 = 15
The highest common factor of both numbers is 315
Since 315 is a factor of 3150, all of its factors are common.
