Is 2060 a prime number or a composite number?
2060 is not a prime number because any number ending in zero can be divided by 10. So, it is a composite number.
MISTAKEN is the answer for this puzzle: * letters 1234 are MIST (climate condition)
* letters 678 are KEN (a name) * letters 478 are TEN (a number) * letters 1457 are MTAE (can be rearranged to spell MATE, a challenge in chess games.)
Is 509 a prime number or a composite number?
Prime. Besides ' 1 ' and itself, it has no other factors.
17 is not a composite number because composite numbers have other factors aside from 1 and itself.
Factors of 17 are only 1 and 17, thus, 17 is a prime number.
612 is a composite number: its factors are 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 153, 204, 306 and 612.

Which is NOT a composite number 37 69 84 121?
It is 37 because it has only 2 factors which are itself and one
Why are prime numbers used to create codes comparied to composite numbers?
Consider two very large primes, P and Q, each a hundred of digits or more in length. Their product is the semi-prime S. Given S, it is extremely difficult to find P or Q. If P and Q are sufficiently large, even very fast computers will take a long time to factorise S.
But, given S and P it is simple to find Q. So if S is used for encryption and P is the key, then anyone who knows P can easily decrypt the message but someone who does not know P will be unable to do so.

Show me the work to know if 0 is prime or 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.
Which is a composite number 21 or 2?
21 is the composite number because it's an odd number. 2 cannot be a composite number because it's even.
