Is 4 Prime?
Check if 4 is a prime number. A prime number is only divisible by 1 and itself.
Result:
✗ NO — 4 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 4 is prime, we need to verify that no number from 2 to √4 divides it evenly.
Step 2
Check if Even
4 is an even number because 4 ÷ 2 = 2 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, 4 is NOT prime.
