WebJun 2, 2024 · Therefore, the smallest number of steps is the lowest sum of n's factors. Since addition increases at a lower rate than multiplication, we need to find the factorisation for n with the smallest factors - the prime factors for n. Hence, the number of steps is the sum of the prime factors of n.
