If n is anumber is 2n prime or composite?
Prime if n=1, composite otherwise.
Is 6n2 plus 27 a prime number or a composite number?
Composite. It is divisible by 3 for any n.
What is the prime of 525?
Are you asking is 525 prime? The a nswer is no. It is a composite number. Are you aski ng what is the prime factorizatio n of 525? Prime factorizatio n of 525 = 3 * 5 * 5 * 7
Is there a biggest composite number?
No, if you think that you have it, you can always find one that is larger. Take, for example you find an even composite number (all even numbers, except 2 - which is the only even prime, are composite). Call this number N. Now add 2 to N for N+2, which is also even, so it is also a composite. What about odd composites: if you find an odd composite(M), then add 1 to it: odd+odd=even, so M+1 is even, which is also composite. You can keep going forever.
How do you find a number is prime or composite?
One way is to divide by all smaller numbers, up to the square root of that number. In practice, you can omit even numbers (except 2), and any number which you know is prime. Thus, for any number up to 120, it is enough to try to divide by 2, 3, 5, 7. If any of these divisions yields an integer, then the number you divided by is a factor - and your original number is composite.
If n is anumber is 2n prime or composite?
Prime if n=1, composite otherwise.
Is 2n prime or composite?
2 is a prime number. 2 times anything but 1 is composite.
Why must the product of any two numbers greater than 1 be a composite number?
A composite number is a positive integer which has a positive divisor other than one or itself. In other words, if 0 < n is an integer and there are integers 1 < a, b < n such that n = a × b then n is composite. By definition, every integer greater than one is either a prime number or a composite number. The number one is a unit - it is neither prime nor composite. For example, the integer 14 is a composite number because it can be factored as 2 × 7.
What is the only n number that is neither prime or composite?
It is one
Is 6n2 plus 27 a prime number or a composite number?
Composite. It is divisible by 3 for any n.
What is the prime of 525?
Are you asking is 525 prime? The a nswer is no. It is a composite number. Are you aski ng what is the prime factorizatio n of 525? Prime factorizatio n of 525 = 3 * 5 * 5 * 7
How do you program if it is a prime or composite?
The easiest, but not the most efficient way, to program this is to take your number "n" and test all the numbers from 2 to n-1 to see if they divide n, if none of them do, then n is prime.
What is the Program for composite and prime numbers in c?
#include<iostream.h> #include<conio.h> int main() { int i,n; clrscr(); cout<<"PROGRAM TO CHECK IF THE NUMBER IS PRIME OR NOT:"<<endl; cout<<"Enter a number:"; cin>>n; for(int i=2;i<n;i++) { if(n%i==0) cout<<"\nTHE NUMBER IS COMPOSITE"<<endl; else cout<<"\nTHE NUMBER IS PRIME"<<endl; } return 0; }
Is 1 726 composite number or prime number?
1726 is certainly not a prime number as it is even and n\hewnce divisible by 2 ... a prime number is one that can only be divided by 1 and by itself, nothing else 1726 is then a composite number
What number has only 6 prime numbers?
Any number of the form n = a*b*c*d*e*f where a, b, c, d, e and f are different prime numbers. n has 26 = 64 factors in total, of which 1 is the number 1 (neither prime nor composite), 6 are prime, and the remaining 57 are composite.
Suppose you are given a number n and are told that 1 and the number n divide into n Does that mean n is prime?
No. All integers are divisible by 1 and themselves. Prime numbers are only divisible by 1 and themselves. Since you were not told that only 1 and n divide into n, you do not know if it is prime. Also, if n = 1, it is neither a prime number nor a composite number.
How to find if a number is prime or composite with C programming?
#include<stdio.h> #include<conio.h> void main() { clrscr(); int n,i,np=0;//np is boolean operator (true/false) printf("\n Enter a number :"); scanf("%d",&n); for(i=2;i<=(n-1);i++) /*we know that a number which is divisible by 1 and divisible by itself Is A PRIME NUMBER. So no need to check n divisible by 1 and divisible by itself */ { if(n%i==0) { np=1; break; //come out of for loop } } if(np==1) // in if statement np=1 ,it confirms that number is composite. { printf("Sorry,its composite number %d",n); } else { printf("it is a prime number %d",n); } OUTPUT: Enter a Number: 12 Sorry its a composite number 12 Enter a number 17 it is a prime number 17
