What are the Math terms abundant perfect and deficient?
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
Can you describe a number by both the number of its factors and the kinds of its factors?
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
Is 2 divisible why?
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.
How do you shrink a number by the scale factor of 2?
You divide the number by 2
What is the GCF of 2 and any even number?
The GCF of 2 and any even number is 2.
Is 26 deficient number?
Yes, 26 is a deficient number. A deficient number is one for which the sum of its proper divisors is less than the number itself. The proper divisors of 26 are 1, 2, and 13, which sum to 16, less than 26. Therefore, 26 is classified as a deficient number.
Is deficient a number?
no. its a type of number. as in, a number can be deficient.
Is 64 a deficient number?
32+16+8+4+2+1=63. 64 is deficient.
Is 8 an abundant number or a deficient number?
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
Is the number 17 a Deficient number?
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.
Is 94 a deficient number?
yes -- 2*94 > 144
Is 55 a abundant number or a deficient number?
55 is deficient.
Is 24 an deficient number?
NO- 24 is not deficient.
Is 38 deficient?
A number is considered deficient if the sum of its proper divisors is less than the number itself. For 38, the proper divisors are 1, 2, and 19, which sum to 22. Since 22 is less than 38, this means that 38 is indeed a deficient number.
What is a deficient number?
A deficient number is a number with its proper factors equalling a lower number than itself.
Is the number 25 abundant deficient or perfect number?
It's deficient
Is the number 32 an abundant deficient or perfect number?
The proper divisors of 32 are 1, 2, 4, 8, and 16. They add up to 31, so 32 is deficient.
