1, 3 and 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 LCM is: 630just multiply 90*63 and what i do is go google and look up least common multiple calculator and there you have different options and pick the one that best fits your answer
The same as the GCF of 63 and 45 (where 45 is the remainder of the division of 927 by 63).
