What is prime factors numbers?

Every positive integer greater than 1 can be expressed as the product of a unique set of prime factors. The count of these factors is the prime factors number for the number.

1, 2, 5 and 10


Is the number 8 a prime or composite number?

8 is a composite number because it has more than 2 unique factors. The following are the factors of 8: 1, 2, 4 and 8


Why is it important that 1 is not prime?

The Fundamental Theorem of Arithmetic states that there is a unique factorisation for any integer - up to the order of the factors. This means that for any number the list of its factors and their multiplicities is unique. That statement is no longer true if 1 is considered to be a prime.


What iis 73 divisible by?

1 and itself, as 73 is a prime number.


Is 39 a prime o composite?

A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 39 iis composite.

How is 1 a unique number?

The number one has the unique property of multiplicative identity: any number times 1 is the same number.


How can you find a number with thirteen factors?

A factor is a number that can be multiplied by another whole number to equal your original number.For example: The factors of 10 are - 1, 2, 5, 10 (10 has 4 unique factors)To find a number with 13 factors, it must be fairly large.We know the number you're looking for will have at least 2 factors, 1 and itself.So we only need to find 11 more.In fact, we can choose factors and make the number ourselves!Remember, factors must be unique. They cannot repeat. A handy way to do this is to use prime numbers.1, 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, and our number. (13 factors)To find your number, multiply ALL of the prime numbers together. (Not 1, and not our number)2*3*5*7*11*13*17*19*23*29*31 = ???You'll find that the number you're looking for is200,560,490,130In fact, this number is the smallest composite number with the first 11 primes as factors!


Why is number 1 not a composite number?

A composite number is a number that has additional factors besides ' 1 ' and itself. The number ' 1 ' has no additional factors besides ' 1 ' and itself. So it's not a composite number.


What are the factors of 2?

The only factors of 2 are 1 and 2. The factors of a prime number are 1 and the number itself.


Why 0 and 1 are not prime numbers?

A prime number is a numbe whos factors are 1 and its self such as 5 the only factors of 5 are 1 and 5 but the number 1 has factors of 1 and 1 those are the same number therefore 1 has facotr(s) of 1 and zerohas factors


What numbers are prime numbers?

Prime numbers are numbers that are only divisible by 1 and the number itself. Some examples of prime numbers are:1,2,3,5,7,11,13,17,19,23,27,29,31,37,41,etc.Prime numbers can go on forever; you just have to find out if its only factors are 1 and itself.Example:9 is not a prime number because other than 1 and 9, it is also divisable by 3.13 is a prime number because its only factors to equal 13 are 1 and 13.Even numbers, with the exception of 0 and 2, cannot be prime numbers.I'm a different person:1 isn't a prime number although many people think it is. this is because a prime number is divisible by itself and 1 but in this case it is the same number so this time 1 isn't a prime number. The definition is that a prime number is a natural number (integers 1 and greater) that has exactly two unique factors: 1 and itself. The number 1 does not have two unique factors.


What number has the largest number of factors from 1-100?

What is a number with exactly two factors called?

a prime number. it will have the factors 1 and it's self. ie. x has factors 1 and xA number with only two factors is a prime number


Why aren't 0 and 1 prime factors?

The fundamental theorem of arithmetic states that any number greater then 1 can be expressed as the product of a unique set of primes. i.e. 6=3x2. If 1 was a prime number then 6=3x2x1=3x2x1x1 which means that the set of primes in no longer unique. They wanted the theorem to work, so mathematicians decided 1 can't be a prime number. Same goes for 0 becasue if 0 was a prime number then 0=0x2=0x3.


Why is the number 1 not composite or prime?

By definition, 1 is not prime. A prime number has exactly two unique natural number divisors; itself and one. You can understand '1 and 1' to be two numbers, but they are not unique. The same reasoning brings us to the conclusion that 1 is not composite; a composite number can be divided without remainder by at least one integer other than itself and 1.


What factors do not include the number itself?

the proper factors are the factors of a number not including the number itself, or 1.


What are the factors and prime factors of 7?

What is a prime number and what is a composite number?

A prime number is a number which has no factors except 1 and itself. For example: 107 is prime because its factors are 1 and 107. A composite number is a number which has more that 1 and itself for factors. For example: 14 is composite because its factors are 1, 2, 7, and 14.


Why do you think mathmaticians decided not to call 1 a prime number?

A prime number has two factors, 1 and itself. 1 is not considered a prime number as its factors are 1. Following the rule for primes, you could say that its factors are 1 and 1, but 1 and 1 are obviously the same number.


What is a number greater than one with more than two factors?

Every number greater than 1 has 1 and the number itself as factors. If it has no other factors besides these two factors, it is a prime number. If it has more factors than 1 and itself, it is a composite number.


All the factors of 1 260?

There are a few factors for the number 1,260. The factors for this number are 1,2,4,5,10,13,20,26,52,65,130 and 260.


What are two factors of each number other than 1 and the number itself to determine that the number is composite?

If a number has additional factors (other than 1 and itself) then it is a composite number. If the only two factors are 1 and itself, then the number is prime.
