A number that is greater than one whose only divisors equal one and itself?
That is called a prime number.
What is a number less than 1 whose only divisors are 1 and itself?
There are no numbers that fit your description.
What is the divisors of 5?
Because five is a prime number its only divisors are 1 and itself.
Why 89 is a prime number?
The only numbers which divide into 89 exactly are 1 and 89. These are called factors or divisors. Any number which has exactly 2 divisors (1 and the number itself) is a prime number.
What is the value of 13?
13 is a Prime number whose only factors are itself and one
A number that is greater than one whose only divisors equal one and itself?
That is called a prime number.
What is a number less than 1 whose only divisors are 1 and itself?
There are no numbers that fit your description.
What are the divisors of 11?
Since 11 is a prime number, its only divisors are 1 and itself.
What is the divisors of 5?
Because five is a prime number its only divisors are 1 and itself.
What are the divisors of the number 47.?
47 is prime. Its only factors are 1 and itself.
What is the divisor for 71?
71 is a prime number so its only divisors are 1 and itself.
Is 31 an abundent number?
A perfect number is a number that is the sum of its divisors (the divisors exclude the number itself).When the sum of the divisors is greater than a number then that number is abundant.As the number itself is excluded from the divisors then the only divisor of 31 is 1.So, 31 is a deficient number.Note : The first few abundant numbers are 12,18,20,24,30 ... and these continue to be even. The first abundant odd number is 945 = 33 x 5 x 7 for which its divisors total 975.
Do bigger numbers necessarily have more divisors?
No they do not, take a big prime number and compare it to a smaller composite number. The number 6833 as only two factors (divisors), namely 1 and itself. But the number 68 which is much smaller has more factors or divisors. 68 has 2 and 4 and 17 and 1 and itself which is already more divisors than 6833.
Why is 3 not a composite number?
The only factors or divisors or 3 are 1 and the number 3 itself. The definition of a prime is a number whose only factors are 1 and itself so 3 fits this definition.Any composite number can be broken down into a product of primes. If you try, you will see there is not product of primes that equals 3.
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.
Why 89 is a prime number?
The only numbers which divide into 89 exactly are 1 and 89. These are called factors or divisors. Any number which has exactly 2 divisors (1 and the number itself) is a prime number.
How to know whether it is a prime number or not?
A number is prime if it is a positive integer which has only two divisors: itself and 1.
