What is the HCF of 80?

Answer 1

Oh, dude, the Highest Common Factor of 80? That's just the biggest number that can divide evenly into 80. So, like, the HCF of 80 is 80 itself because it's the highest number that can go into 80 without leaving a remainder. Easy peasy, right?

Answer 2

Ah, the Highest Common Factor, what a happy little concept. Let's take a moment to appreciate the number 80. Its factors are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80. The highest common factor among these numbers is 40, which means it is the largest number that can evenly divide both 80 and itself.

Answer 3

The Highest Common Factor (HCF) of 80 is the largest positive integer that divides 80 without leaving a remainder. The factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80. The HCF of 80 is 40, as it is the largest factor that is common to all of the numbers listed above.

Answer 4

A single number cannot have a highest common factor because "common" refers to factors that two or more numbers have in common. You have only one number.

Answer 5

You need at least two numbers to find a GCF.
