A single number cannot have a "common" factor, though it has factors: 1, 5,11.
If you ask for the factors of 40 and 50, then for 40 you have 1, 2, 4, 5, 8, 10, 20, 40, while for 50 you have 1, 2, 5, 10, 25 and 50.
In both of those sets you van find 1, 2, 5,10. Because they are in both sets they are "common" to both 40 and 50.
The highest of the common ones is 10, so this is the "highest common factor" of 40 and 50.
No higher factor will divide into both 40 and 50.

What is the HCF of 20 and 55?
The Highest Common Factor (HCF) of 20 and 55 is the largest positive integer that divides both 20 and 55 without leaving a remainder. To find the HCF, we need to determine the common factors of 20 and 55, which are 1 and 5. The highest common factor among these common factors is 5. Therefore, the HCF of 20 and 55 is 5.
What is the highest common factor of 55 138 and 143?
The GCF is 1.
What is he highest common factor of 55 and 155?
To find the highest common factor (HCF) of 55 and 155, we first need to list the factors of each number. The factors of 55 are 1, 5, 11, and 55. The factors of 155 are 1, 5, 31, and 155. The highest common factor is the largest number that both lists share, which in this case is 5. Therefore, the highest common factor of 55 and 155 is 5.
