The sum of factors indicates whether numbers are abundant, perfect, or deficient.
Calculate the sum of factors excluding the number itself.
After factorizing the input number, calculate the sum of factors using an accumulator variable.
Compare the sum with the number itself. If the sum is less than the number, it's a deficient number; otherwise, if it's greater, it's an abundant number. The sum of factors, if equal to the factorized number, identifies a perfect number.
