Explain why the highest common factor between 2 distinct prime numbers is one

Because the only factors a prime number has is itself and one, so both prime numbers would have only themselves and one, and one is the only one they have in common.

The highest common factor between 2 distinct prime numbers is 1 because the only factors that creates a prime number is 1 times itself. This is only true when using full numbers. In this case, we are excluding fractions and decimals.

Step-by-step explanation:

For example: 2 and 41

1 * 2 = 2; Nothing else when multipled equals 2

1 * 41 = 41; Nothing else when multipled equals 41
