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

Is 70 a abunant or deficient or perfect?

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.

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

How do you show 9 as a deficient number?

Deficient number From Wikipedia, the free encyclopediaIn mathematics, a deficient number or defective number is a number n for which &Iuml;&fnof;(n) < 2n. Here &Iuml;&fnof;(n) is the sum-of-divisors function: the sum of all positive divisors of n, including nitself. An equivalent definition is that the sum of all proper divisors of the number (divisors other than the number itself) is less than the number. The value 2n &acirc;&circ;&rsquo; &Iuml;&fnof;(n) is called the deficiency of n.The first few deficient numbers are: 1, 2, 3, 4, 5, 7, 8, 9, 10, 11, 13, 14, 15, 16, 17, 19, 21, 22, 23, 25, 26, 27, &acirc;&euro;&brvbar; (sequence A005100 in OEIS)As an example, consider the number 21. Its divisors are 1, 3, 7 and 21, and their sum is 32. Because 32 is less than 2 &Atilde;&mdash; 21, the number 21 is deficient. Its deficiency is 2 &Atilde;&mdash; 21 &acirc;&circ;&rsquo; 32 = 10.An infinite number of both even and odd deficient numbers exist. For example, all odd numbers with one or two distinct prime factors, and all proper divisors of deficient or perfect numbers are deficient.Closely related to deficient numbers are perfect numbers with &Iuml;&fnof;(n) = 2n, and abundant numbers with &Iuml;&fnof;(n) > 2n. The natural numbers were first classified as either deficient, perfect or abundant byNicomachus in his Introductio Arithmetica (circa 100).

Is the number 13 an abundant number?

No it isn't. The factor sum is 14 and the double of number is 26 so it is not an abundant number

Is 28 abundant deficient perferct or near perfect?

An integer is a perfect number if it is equal to the sum of its positive divisors, not including the number itself.The divisors of 28 are : 1, 2, 4, 7 and 14....and these sum to 28. Thus 28 is a perfect number.In Number Theory there is a theorem that, If 2k - 1 is prime then 2k-1(2k - 1) is perfect.If we put k = 3 then 2k - 1 = 23 - 1 = 8 - 1 = 7 is prime.And, 23-1 (23 - 1) = 22(8 - 1) = 4 x 7 = the resultant perfect number.

Is the number 14 a perfect square?


What is the perfect square number?

A perfect square number is a number that can be expressed as the product of two same common integers. For instance, 16 is a perfect square since it is expressed as 4 x 4. 14 is not the perfect square since it can't be expressed as two common integers. The factors of 14 are 2 and 7.
