Write a method called perfectNumbers that accepts an integermaximum as its parameter and prints all “perfect numbers” up to and including that maximum. A perfect number is an integer that is equal to the sum of its proper factors, that is, all numbers that evenly divide it other than 1 and itself. For example, 28 is a perfect number because 1 + 2 + 4 + 7 + 14 = 28. The call perfectNumbers(500); should produce the following output:Perfect numbers up to 500: 6 28 496
