Can you find a common characteristic shared by the numbers 6 and 28 other than that they are both even numbers divisible by 2?
They are both perfect numbers. A perfect number is one whose factors (except for the number itself) add to equal the number.6 = 1 + 2 + 328 = 1 + 2 + 4 + 7 + 14They are also both triangular numbers - sums of the integers in sequence.1 = 11 + 2 = 31 + 2 + 3 = 61 + 2 + 3 + 4 = 101 + 2 + 3 + 4 + 5 = 151 + 2 + 3 + 4 + 5 + 6 = 211 + 2 + 3 + 4 + 5 + 6 + 7 = 28
