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. 47 is prime.
Prime numbers have two factors. Composite numbers have more than two.
Prime numbers have only two factors. Composite numbers have more than two.
It tells you if a number is prime or composite and it also gives you a few factors of the number.
it is a composite number because you can tell from the 8 that it is an even number, and even numbers can always be divided.
48 is not a prime number it can be divide by 8, 2 and 4
All numbers that only have one and itself as factors are prime. Therefore, to tell if a number is prime simply find it's factors. If it has more than two factors than it is not a prime number, otherwise it is composite.
Prime numbers have no divisibles.
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.
A good way to instantly tell if a number is prime or composite is to learn some tricks to tell if a number divides by certain numbers. For instance, if a number is even, we know it is composite as it must be divisible by 2. If a number ends in 0 or 5, then it also cannot be prime as it would be divisible by 5. In this case, the number ends in 5, so we can tell it must be composite and cannot be prime.
101, 173 and 911 are all prime numbers. 173911 is not.
It is even and therefore composite.
You cannot. If a number is even - other than 2 - then it is a composite number. However, if it is odd, it is not easily possible to tell whether it is prime or composite.
