A perfect octave
The least one-digit number that is a perfect square is 0, as (0^2 = 0). However, if we consider only positive one-digit numbers, then the least perfect square is 1, since (1^2 = 1).
The sum of the 1st perfect number and 2nd perfect number is. . . 34!

Pythagoras
64: 1, 2, 4, 8, 16, 32, 64Tip: To find the number, consider that if there are an odd number of factors, the number must be a perfect square, because a perfect square has one factor that is multiplied by itself. 64: 1, 2, 4, 8, 16, 32, 64Tip: To find the number, consider that if there are an odd number of factors, the number must be a perfect square, because a perfect square has one factor that is multiplied by itself.
