READER QUESTION: Can You Prove That All Integers Divisible by 2 Are NOT Prime?

No

Okay why not?

To disprove an “all” statement in math, you only need one counterexample. If we can find an integer that is simultaneously divisible by 2 and prime, then we can disprove the entire statement.

Since 2 is divisible by 2 AND is prime, then we can say the statement “All Integers Divisible by 2 Are NOT Prime” is FALSE.
