To find the highest common factor (HCF) of 20, 40, and 50, we first need to identify the factors of each number. The factors of 20 are 1, 2, 4, 5, 10, and 20; the factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40; and the factors of 50 are 1, 2, 5, 10, 25, and 50. The highest common factor among these three numbers is 10, as it is the largest number that divides all three numbers without leaving a remainder.

50% off of 40= 50% discount applied to 40= 40 - (50% * 40)= 40 - (0.50 * 40)= 40 - 20= 20
The highest common factor (HCF) of 400 and 250 is 50. To find the HCF, you can list the factors of each number and identify the greatest number they have in common. The factors of 400 are 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, and 400. The factors of 250 are 1, 2, 5, 10, 25, 50, 125, and 250. The greatest number that appears in both lists is 50, making it the HCF.
The HCF of the numbers 40 and 44 is 4.

20 is 50% of 40.
It is 1 but the HCF is 2
50% off of 40= 50% discount applied to 40= 40 - (50% * 40)= 40 - (0.50 * 40)= 40 - 20= 20
20/50 = 40/100 = 40%
