Is prime?
Result: ✗ NO — 80 is NOT a prime number
Step-by-Step Solution
Step 1 What is a Prime Number?

A prime number is a natural number greater than 1 that has exactly two factors: 1 and itself.


To check if 80 is prime, we need to verify that no number from 2 to √80 divides it evenly.

Step 2 Check if Even

80 is an even number because 80 ÷ 2 = 40 with no remainder.


All even numbers greater than 2 are divisible by 2, so they have at least three factors: 1, 2, and themselves.


Therefore, 80 is NOT prime.
