72 is an abundant number because the sum of its positive divisors, not including 72 itself, is larger than 72.
Positive divisors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72.
1 + 2 + 3 + 4 + 6 + 8 + 9 + 12 + 18 + 24 + 36 = 123 > 72
(if an integer is larger than the sum of its positive divisors , not including the integer itself, then that integer is called a deficient number, such as prime or power of prime numbers or numbers like 10 are).
deficient
It is a deficient number. The first abundant number is 12. 12: 1,2,3,4,6,12 which equal 28 28>(12*2) and the abundance is 28-(12*2)=4
A perfect number is one with factors (apart from itself) that sum to give the original number. An abundant number is one where this sum is greater than the original number. A deficient number is one where the sum is less than the original number. The factors of 75 are 1, 3, 5, 15 and 25. The sum of these numbers is 49. Thus 75 is a deficient number.
it is perfect i believe the factors are 1,2,4,7,and 14
To find out if a number is abundant, perfect or deficient, you first need to split it into its prime factors: 34 = 2x17 The next step would be to find any combinations, but as we have only 2 prime factors, those are the two we'll work with. You add these together, with 1, and get 20. When this sums to less than the original number it's a deficient number. 20 is less than 34, and so 34 is a deficient number.
