The greatest common factor (GCF) of 45, 60, and 90 is 15. To find the GCF, you need to determine the common factors of the numbers and then identify the greatest one they all share. The factors of 45 are 1, 3, 5, 9, 15, and 45. The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60. The factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90. The greatest common factor among them is 15.
The Greatest Common Factor (GCF) is: 15
15
The highest common integral factor is 5, because 25 = 52, five is an integral factor of both 45 and 60, and 25 is not an integral factor of either 45 or 60.
The GCF is 5.
