Result: ✗ NO — 126 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 126 is prime, we need to verify that no number from 2 to √126 divides it evenly.

Step 2 Check if Even

126 is an even number because 126 ÷ 2 = 63 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, 126 is NOT prime.
