The factors of 45 are: 1, 3, 5, 9, 15, 45 The factors of 63 are: 1, 3, 7, 9, 21, 63
The highest common factor is 9
To find the greatest common factor (GCF) of 63, 36, and 45, we need to determine the largest number that divides evenly into all three numbers. First, we find the factors of each number: 63 (1, 3, 7, 9, 21, 63), 36 (1, 2, 3, 4, 6, 9, 12, 18, 36), and 45 (1, 3, 5, 9, 15, 45). The GCF is the largest number that appears in all three lists, which is 9. Therefore, the greatest common factor of 63, 36, and 45 is 9.
The factors of 45 are: 1, 3, 5, 9, 15, 45The factors of 63 are: 1, 3, 7, 9, 21, 63The common factors are: 1, 3, 9
