You need to find work out the factors of both 45 and 105 separately, and then find which match both numbers. 45 - 1, 3, 5, 9, 15, 45 105 - 1, 3, 5, 7, 15, 21, 35, 105 The numbers that match both 45 and 105 are 1, 3, 5, and 15. 15 would therefore be called the Greatest Common Factor (GCF).
The factors of 75 are: 1, 3, 5, 15, 25, 75 The factors of 90 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90 The factors of 105 are: 1, 3, 5, 7, 15, 21, 35, 105
The factors of 315 are: 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
The greatest common factor of 45 and 105 is 15.
