They refer to the sum of a number's proper divisors, defined here as all of the factors except the number itself.a perfect number equals the sum of its proper divisorsa deficient number is greater than the sum of its proper divisorsan abundant number is less than the sum of its proper divisors
There are more than just prime and composite, there are 3 other types which you can describe a number by the kind of factors. They are abundant number, deficient number, and perfect number. An abundant number is a number which if its factors were all added up , the sum would be greater than the number itself. A deficient number is a number in which if all its factors were added up the sum would be less than the number itself. A perfect number is in which a numbers factors are added up and the sum will be the same number as the number itself. Example of abundant number: 12 because these are its factors, 1+2+3+4+6 which equals 16 and 16 is greater than 12. Example of a deficient number: 15 because 15's factors are 1+3+5 which equals 9 and 9 is less than 15. Example of a perfect number: 6 because 6's factors are 1+2+3 which equals 6 and 6 is the same as 6
2 is a prime number, so its only divisors are 1 and itself. Any other number having a divisibility of 2 is an even number.
You divide the number by 2
The GCF of 2 and any even number is 2.
no. its a type of number. as in, a number can be deficient.
32+16+8+4+2+1=63. 64 is 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
17 is a deficient number because half the sum its factors is less than 17 [(1 + 17)/2 = 9)]. All odd numbers less than 945 are deficient.
yes -- 2*94 > 144
55 is deficient.
NO- 24 is not deficient.
It's deficient
A deficient number is a number with its proper factors equalling a lower number than itself.
deficient
It is deficient.
The proper divisors of 32 are 1, 2, 4, 8, and 16. They add up to 31, so 32 is deficient.
