14 is deficient. It is less than the sum of it's divisors. In mathematics, a deficient number or defective number is a number n for which σ(n) < 2n. Here σ(n) is the sum-of-divisors function: the sum of all positive divisors of n, including n itself Proof.. divisors of 14 are 1,2, and 7 and 14. Now, 2n=28 and and the sum the all the divisors including 14 is 24<28
To compare -20 and 14, a positive number (in this case, 14), is always greater than any negative number.
If the sum of all a number's factors (apart from itself) is equal to the original number, then the number is perfect. If this sum is less than the number, it is deficient. If the sum is more than the number, it is abundant. The factors of 70 are: 1, 2, 5, 7, 10, 14, 35 and 70. 1+2+5+7+10+14+35 = 74. Thus the number 70 is abundant.
The number is less than 18.
There is no such number.
