Is 107 Prime?
Check if 107 is a prime number. A prime number is only divisible by 1 and itself.
Result:
✓ YES — 107 is 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 107 is prime, we need to verify that no number from 2 to √107 divides it evenly.
Step 2
Determine Testing Range
Since 107 is odd, we only need to check odd divisors.
We only need to test up to √107 ≈ 10.34, which rounds down to 10.
If 107 has a factor larger than √107, it must also have a corresponding factor smaller than √107.
Step 3
Test Odd Divisors
Testing: 3, 5, 7, ... up to 10
107 ÷ 3 = 35 remainder 2
107 ÷ 5 = 21 remainder 2
107 ÷ 7 = 15 remainder 2
107 ÷ 9 = 11 remainder 8
None of these numbers divide 107 evenly.
Step 4
Conclusion
107 has no divisors between 2 and 10.
The only factors of 107 are 1 and 107 itself.
Therefore, 107 is a PRIME number!
