Is 84 Prime?

Check if 84 is a prime number. A prime number is only divisible by 1 and itself.

Result: ✗ NO — 84 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 84 is prime, we need to verify that no number from 2 to √84 divides it evenly.

Step 2 Check if Even

84 is an even number because 84 ÷ 2 = 42 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, 84 is NOT prime.
