9, 99, 999 are three.
8, 10, and 12 are 3 composite numbers. They are composite because they ahve more than 2 factors.
Prime numbers have no divisibles.
Prime numbers have only two factors. Composite numbers have more than two.
Prime numbers have two factors. Composite numbers have more than two.
Prime numbers have only 2 factors which are themselves and one whereas composite numbers have more than 2 factors
4, 6, 10.They are composite because they have more factors than just 1 and themselves.There are 2 types of numbers, prime and composite. Prime means it's only factors are 1 and itself, ex. 7's only factors are 1 and 7.Composite means it has more than 2 factors. A factor is a number you multiply by another number to get another. Example, 4 is composite because it's factors are 1,4, and 2.
Because both numbers have more than two factors which makes them composite numbers.
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.
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.
Without a specific range, that's an infinite list.
blah blah blah find it out yourself. I know but i won't tell you...
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.
48 is not a prime number it can be divide by 8, 2 and 4
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.
It tells you if a number is prime or composite and it also gives you a few factors of the number.
well first off all even numbers are composite (except 2). you can fist off tell if a number can be divided by three by adding up its digits such as 423. We know that 3 can go into this because the digits add up to 423. please take third grade again to learn the rest of the rueles
A composite number is a number that can be divided by multiple other integer numbers other then 1 and the number itself. For instance 4,567,278 can be divided by 2.
Because the number 4567278 is divisible by numbers other than 1 and by itself.
32 is not a prime because 2 is a factor of all even numbers. 95 is not a prime because all numbers greater than 5 that end in a 5 or 0 are composite numbers.
The numbers with only three factors are squares of prime numbers.
405 is composite. Anything that is divisible by more than two numbers (itself and 1) is considered a composite number. Looking at the number, you can tell that it is divisible by 5 because it ends in a 5. There will be more factors, but finding one that is not 1 or itself will cause the number to be composite.
Try dividing by some numbers. The larger the number, the more numbers you have to divide by. It is enough to test division by 2, and all the odd numbers up to the square root of the number. For very large numbers, this is not efficient. There are more efficient methods, but they are also more difficult to understand.
