Factors definition, one of the elements contributing to a particular result or situation: Poverty is only one of the factors in crime. Then your main method would call that, get the factorization List, and either just print it as-is (it will have opening and closing square brackets, which may be fine) or you can write another method that formats it as you like. The main tool for the feat is the prime number decomposition theorem. Multiply the elements of f to reproduce the input value. Notably, if an integer has only two factors, 1 and itself, then it is a prime number. k is a integer giving the number of replications.
