...Dashie Posted February 21, 2014 Report Share Posted February 21, 2014 "It is a composite number, its proper divisors being 1, 2, 4, 7, and 14. Twenty-eight is the second perfect number. As a perfect number, it is related to the Mersenne prime 7, since 22(23 - 1) = 28. The next perfect number is 496, the previous being 6. Twenty-eight is the third Granville number. The next Granville number is 96, the previous being 24. Twenty-eight is the sum of the totient function for the first nine integers. Twenty-eight is not the aliquot sum of any number other than itself and is therefore not a component in an aliquot sequence. Since the greatest prime factor of 282 + 1 = 785 is 157, which is more than 28 twice, 28 is a Størmer number. Twenty-eight is a harmonic divisor number, a happy number, a triangular number, a hexagonal number, and a centered nonagonal number." Link to comment Share on other sites More sharing options...
