# How to get all the divisors of given number in Java?

##
__Problem Description__ :

Write a program in Java that prints all the divisors of any given number.

##
__Concept__ :

Divisors means numbers that are evenly divisible by given number. All the divisors should be less than or equal to given number. For example - number 12 has 6 divisors 1,2,3,4,6,12. We can solve this problem either using brute force approach or some efficient algorithm.

##
__Java Program__ :

###
1) __Brute Force__ :

It will take lot of time if number is very large because in for loop one by one we are checking each number.

###
2) __Efficient Algorithm__ :

This is an efficient algorithm because here we are not checking each number, for loop is running until square root of given number.

##
__Output__ :
