## Is 17 abundant deficient or perfect?

Deficient numbers occur more frequently than abundant numbers.

In other words, the sum of the proper divisors of most numbers is less than the numbers themselves.

Examples of deficient numbers include 1, 2, 3, 4, 5, 7, 8, 9, 10, 11, 13, 14, 15, 16, 17, 19, 21, 22, and 23..

## Is 95 abundant or deficient?

Yes, 95 is a deficient number, that is to say 95 is a natural number that is strictly larger than the sum of its proper divisors, i.e., the divisors of 95 without 95 itself (that is 1 + 5 + 19 = 25).

## Is 30 a perfect number?

Perfect number, a positive integer that is equal to the sum of its proper divisors. The smallest perfect number is 6, which is the sum of 1, 2, and 3. Other perfect numbers are 28, 496, and 8,128.

## What is the smallest abundant number?

In number theory, an abundant number or excessive number is a number that is smaller than the sum of its proper divisors. The integer 12 is the first abundant number. Its proper divisors are 1, 2, 3, 4 and 6 for a total of 16.

## How do you find the divisors of a number?

Given a natural number, calculate sum of all its proper divisors. A proper divisor of a natural number is the divisor that is strictly less than the number. For example, number 20 has 5 proper divisors: 1, 2, 4, 5, 10, and the divisor summation is: 1 + 2 + 4 + 5 + 10 = 22.

## Is 16 an abundant number?

Finding Abundant Numbers If the sum of the proper factors is greater than your actual number, then the number is considered to be an abundant number. … The number 16 is greater than the number 12, so 12 is an abundant number.

## How many numbers is 36 divisible by?

For 36, the answer is: No, 36 is not a prime number. The list of all positive divisors (i.e., the list of all integers that divide 36) is as follows: 1, 2, 3, 4, 6, 9, 12, 18, 36. For 36 to be a prime number, it would have been required that 36 has only two divisors, i.e., itself and 1.

## What are the divisors of 16?

## What is a number divisible by 3?

If the sum of the digits of a number is divisible by 3, then the number is divisible by 3. Some examples of numbers divisible by 3 are as follows. The number 85203 is divisible by 3 because the sum of its digits 8+5+2+0+3=18 is divisible by 3.

## What are divisors of 15?

The set of all the whole number divisors (natural number factors) of 15 is {1, 3, 5, 15}. The set of all the natural number multiples of 15 is {15, 30, 45, 60, …, 15n, …}. The set of all the whole number multiples of 15 is {0, 15, 30, 45, 60, …, 15n, …}.

## Is 36 a perfect number?

-perfect numbers are 36, 1800, 2700, 17424, … (OEIS A054980).

## Are 60 and 84 Amicable numbers?

Amicable Numbers The Greeks considered the pair of numbers 220 and 284 to be amicable or friendly numbers because the sum of the proper divisors of one of the numbers is the other number. a. 60 and 84 are amicable numbers.

## IS 144 a perfect number?

144 is a perfect square, sure, but the sum of its digits is also a perfect square (9), the product of its digits is also a perfect square (16), and its reverse is also a perfect square (441). … 144 can be written as the sum of two twin primes, namely 71 and 73.
