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
The highest common factor of both numbers is 315
Since 315 is a factor of 3150, all of its factors are common.
90 = 2x3x3x5210 = 2x3x5x7315 = 3x3x5x7GCF = 3x5 = 15
