What is an facts about prime numbers?
Prime numbers are numbers that have only 2 factors, 1 and itself. The number one is not prime or composite. Most prime numbers are odd. There is only one composite even number, 2.
Are even numbers prime numbers?
The only prime number that's even is 2 the rest are odd but that doesn't mean ALL odd numbers are prime. Many are but not most.
How many factors can be used at the most to be a prime number?
Prime numbers only have two factors, one and the number itself.
Is the difference of two prime numbers a prime number?
Not necessarily. 71 is a prime number, 7 is a prime number, and 71-7= 64, which is NOT a prime number. In most cases, the difference of two prime numbers will not be a prime number. All prime numbers greater than 2 will be odd numbers. The difference between two odd numbers will be an even number. Unless that even number is 2, it is not a prime number. Here are some additional examples: 19, 13: difference 6, not prime 23, 7: difference 16, not prime 53, 31: difference 22, not prime 61, 59: difference 2, prime 113, 109: difference 4, not prime 293, 283: difference 10, not prime 331, 101: difference 230, not prime
Are there any more consecutive prime numbers?
The only prime numbers with a difference of 1 are the numbers 2 and 3. More consecutive numbers are not possible, since one of the two would have to be even - and an even number is divisible by 2, and therefore not a prime number (2, of course, is a prime number, but larger even numbers are not).The most you can expect with larger prime numbers is a difference of 2. Very large such "prime twins" are known; a few are 3 and 5; 101 and 103, but much larger ones are known, as well. It is not yet known whether there are an infinite number of twin primes.The only prime numbers with a difference of 1 are the numbers 2 and 3.

Which number less than 1000 has the most different prime factors?
210 has 4, which is the maximum possible. There are other numbers with 4 different prime factors.

Is 118 a prime number?
no it can be divided by two, most even numbers arnt prime
Is the product of 2 numbers a prime number?
The product of two numbers could be either a composite number or a prime number. If one of those numbers is 1 and the other is a prime number, the result is that prime number. If neither number is 1, the product of the two numbers will be a composite number. If one of those numbers is 1 and the other is not a prime number, the product will not be a prime number. So, in most cases, it will be a composite number.
How many factors can be used at the most to be a prime number?
Prime numbers only have two factors, one and the number itself.
Why are all prime numbers except 2 odd?
This is because they are only two factors in that number. It may seem to you that all prime numbers odd, but it is not true. Most of them however, are prime numbers. This is why most of the odd numbers are prime numbers.
What is a mersume prime number?
Let p = any prime number. (2p -1) is called a Mersenne number. Any such number that is prime is called a Mersenne Prime. Father Mersenne wrote a list of numbers of this type which he thought were prime, but a few were not. In fact, most of the large Mersenne numbers are not prime, but all the really large numbers that have been proved to be prime are Mersenne Primes.
Are most even numbers also prime numbers?
No in fact there is only one even prime number A number evenly divisible by itself and 1. Example 4 6 8 not prime numbers because they are all divisible by 2
Why is there more composite numbers than prime numbers?
There are more composite numbers than prime numbers because most numbers have more factors than just 1 and a number itself.
Is the difference of two prime numbers a prime number?

Which type of number is most important to factor?
Composite numbers.
