Then you multiply the number you're investigating with 2, and if the result of this is greater than the sum, it is deficient.Let's check 12 (which is not deficient):12 is divisible by 2, 3, 4, 6, and 12The sum of 2, 3, 4, 6, and 12 is 2712 times 2 is 2424 < 27The sum is greater, so 12 is not deficient.
