Is 1637143983 prime or composite?
1637143983 is not prime. Its prime factorisation is: 3 × 3 × 7321 × 24847.
In the case of this number and one ninth of all integers, the fact that it is composite can be quickly determined by calculating the core digit value, the sum of all digits reduced to one digit. The core digit value of this number is 9, and every single integer with this core digit value is a multiple of 9. This can only prove that a number is composite. A core digit value other than 9 does not prove that a number is prime.
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.
Which numbers are composite numbers?
A composite number is a positive integer, which has a positive divisor other than one or itself.
Is 220 a prime or composite number?
220 is a composite number, as are all whole numbers ending in zero.
Is 28571 a prime number or a composite number?
28571 is prime. It is only evenly divisible by itself and one.
20 = 4*5Thus it can be expressed as a product of two integers each of which is larger than 1.
How do you determine if the number 22 is composite?
2 and 11 can also go into the number 22. If it was prime only 22 and 1 could go into the number.
What are the 15 composite numbers greater than 50 less than 70?
I suggest you look up a table of prime numbers. Any integer treater than one that is not in the table of prime numbers is a composite number.
Is 818 a prime number or a composite number?
818 is a composite number because it is an even number greater than 2.
Are there any number that are neither prime nor composite?
Yes. All prime numbers and composite numbers are positive integers, or whole counting numbers. That leaves infinitely many numbers that are neither prime nor composite. If you intended to narrow the scope of your question to the whole counting numbers or to the positive integers, then there are NO such numbers that are neither. A counting number, however large, will be either prime or composite.
Is number 5 a composite because it has factors 2.5?
The number 5 is prime. Factors refer to whole numbers, not decimals.
Is the number 1155 composite or prime?
1155 ends with 5, which means it is divisible by 5. It is a composite number because it has factors in addition to 1 and itself.
The number 993 is a composite number because you can divide it by 3. A good strategy for figuring this out on your own is adding up all the digits. If you can divide the sum of the digits by any numbers besides 1 and that number than that number will be a composite number. You can do it, just remember this!
Is 330 a prime composite or neither?
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. 330 is composite.
What is the mode if the numbers are- 87 61 84 48 54 73 82 66 90 70?
The mode is the number in a series like this that occurs most often. However, since none of these numbers repeats, we say that there is no mode. (And yes, if more than one number repeats the same number of times, you can more than one mode.)
How does the number of stamens compare to the number of pistols?
Depends on the flower, but usually six: http://en.wikipedia.org/wiki/Stamen
