The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40
The factors of 45 are 1, 3, 5, 9, 15, and 45
The common factors of 40 and 45 are the numbers that can evenly divide both 40 and 45 without leaving a remainder. The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. The factors of 45 are 1, 3, 5, 9, 15, and 45. The only common factor of 40 and 45 is 5.
The GCF of 40 and 45 is 5.The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, and 40The factors of 45 are: 1, 3, 5, 9, 15, and 45The greatest common factor (GCF) is 5.The best way to check your work is to make the numbers a fraction and reduce by the GCF: 40/45 = 8/9. If the number doesn't reduce any further, then your GCF is correct.

The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40.
45 of 40 = 45*40 = 180045 of 40 = 45*40 = 180045 of 40 = 45*40 = 180045 of 40 = 45*40 = 1800
Common factors of 40 and 45 are: 1 and 5.
The greatest common factors of 10 40 and 45 is 5
The GCF of 40, 45, and 90 is 5 The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40 The factors of 45 are 1, 3, 5, 9, 15, and 45 The factors of 90 are 1, 2, 3, 5, 6, 10, 15, 18, 30, 45, and 90 So the greatest common factor is 5.
The Highest Common Factor (HCF) of 45 and 40 is 5. To find the HCF, you need to determine the largest number that divides both 45 and 40 without leaving a remainder. The factors of 45 are 1, 3, 5, 9, 15, and 45, while the factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. The largest number that appears in both lists is 5, making it the HCF of 45 and 40.
40% of 45= 40% * 45= 0.4 * 45= 18
