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
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 are 2 almost perfect numbers between 5 and 20?
Perfect numbers are numbers where all the factors add to that number. For example 6's factors are 1,2, and 3 and 1+2+3=6. Therefore the next perfect number isn't until 28 which is 1,2, 4, 7, 14 where 1+2+4+7+14= 28 An almost perfect number is a number which, when adding all of its proper divisors (all divisors except himself), gives you one less, or one more then the number itlself. Up to now all known almost perfect numbers are 2^n. So to answer your question, the 2 almost perfect numbers between 5 and 20 are 8 and 16. Divisors of 8: 1,2,4 -----> 1+2+4=7 Divisors of 16: 1,2,4,8 -----> 1+2+4+8=15

What are some of the mathematical properties of the number 925?
925 is a number divisible by 5, as its last digit is a 5. It is an odd number. Its divisors are 5, 5, and 37, also all odd numbers. It is a three-digit number.
Is any number with two digits prime?
Not all two-digit numbers are prime. A prime number is defined as a number greater than one that has no positive divisors other than one and itself. While there are several two-digit prime numbers, such as 11, 13, and 17, many two-digit numbers, like 10, 12, and 14, are composite because they have divisors other than one and themselves.

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
