AllFactors.java

package com.TimBuchalka;
//Write a method named printFactors with one parameter of type int named number. If number
//is < 1, the method should print "Invalid Value". The method should print all factors of
//the number. A factor of a number is an integer which divides that number wholly (i.e.
//without leaving a remainder). For example, 3 is a factor of 6 because 3 fully divides 6
//without leaving a remainder. In other words 6 / 3 = 2.
//
//EXAMPLE INPUT/OUTPUT:
//* printFactors(6); → should print 1 2 3 6
//* printFactors(32); → should print 1 2 4 8 16 32
//* printFactors(10); → should print 1 2 5 10
//* printFactors(-1); → should print "Invalid Value" since number is < 1
//
//HINT: Use a while or for loop.
//
//NOTE: When printing numbers, each number can be in its own line. They don't have to be separated by a space.
//
//For example, the printout for printFactors(10); can be:
//
//1
//2
//5
//10
