Prime Factorization of 123
Find the prime factorization of 123. Express 123 as a product of prime numbers.
To find the prime factorization of 123, we need to express it as a product of prime numbers.
We do this by repeatedly dividing by the smallest prime that divides evenly, starting with 2.
A prime number is only divisible by 1 and itself (2, 3, 5, 7, 11, 13, ...).
123 is an odd number, so it is not divisible by 2.
We move on to check the next prime number: 3.
3 is a prime number that divides our current value. We can divide by 3 once:
After dividing by 3, we have 41 remaining.
We are left with 41, which is greater than 1.
41 cannot be divided by any prime smaller than its square root.
Therefore, 41 is itself a prime number and is our final factor.
Now we combine all the prime factors we found:
Expanded form: 123 = 3 × 41
Exponential form: 123 = 3 × 41
We can verify: 3 × 41 = 123 ✓
