Is the number 14 a abundant perfect or deficient number?

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

List all abundant numbers 1 to 49?

An abundant number is any natural number (starting from 1) that is less than the sum of all its divisors excepting itself (the set of "all its divisors excepting itself" is also known as the set of its "proper divisors"). The lowest abundant number is twelve, and the first nine (all of those between one and fourty-nine, inclusive) are: 12 18 20 24 30 36 40 42 48

Are all prime numbers imperfect?

yes. The only divisors of a prime number are itself and 1. Without counting the prime number, the sum of it's divisors is always 1.

What is dividers for math?

Do you mean divisors? If you are, then a divisor is the number that is by divided. That's really all there is to say about divisors. I'm very sorry if this doesn't help.

What is the perfect number and what is the perfect number after six?

A perfect number is a number, which, when adding all of its proper divisors (all divisors except himself) give the number itself Divisors of 6: 1,2,3 ------>1+2+3=6 The next proper number is 28 Divisors of 28:1,2,4,7,14 -------> 1+2+4+7+14=28 All perfect numbers found so far are found using this formula: 2^(p-1)*((2^p)-1), where p, and ((2^p)-1) are prime numbers

How do you find all positive integers N such that the product 2029 x N has exactly three divisors?

There is only 1 value of N that satisfies 2029 x N has exactly three divisors: N = 2029 To have exactly three divisors, the number must be the square of a prime number. 2029 is a prime number with exactly 2 divisors (1 and 2029). Thus the only number with exactly three divisors of which two are 1 and 2029 is 20292 (= 4116841), making N = 2029.

What is a positive divisor?

A divisor is another name for a factor. All counting numbers have divisors. In the equation 3 x 4 = 12, 3 and 4 are divisors of 12. -3 x -4 also equals 12, so some people distinguish between positive and negative divisors. A positive divisor is a divisor that is a positive number.
