The prime factorization of 67 is simply 67 itself. This is because 67 is a prime number.
To explain further, a prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. In other words, a prime number has exactly two distinct positive divisors: 1 and itself. Since 67 can only be divided by 1 and 67 without leaving a remainder, it remains as a singular prime factor.
