If a number is divisible by 3 or more numbers than that number is composite, if not than it is prime.

If a number is divisible by anything other than itself and 1, it's composite.

Knowing the rules of divisibility will help. Also, if you divide the smaller number into the larger one and the answer is an integer, it's a factor.

It is a composite number: it has factors other than 1 and itself.

Yes you canYes. If a number is divisible by anything other than one or itself, it's composite.

A composite number is a positive integer with more than two factors.

Every even number greater than two is composite.

350 is a composite number. it can be divisible by 10, 35, 5, 2 etc. You will find it easier to tell between prime and composite if you know the divisibility rules. one simple one is that if a number ends with zero it is divisible by 10...there are a lot of other divisibility rules.

Any even number is divisible by 2.

No, you only need to determine if the number has any factors besides 1 and itself. If it does, it is a composite number.

Composite numbers have more than two factors. Once you find a third factor, you know your number is composite.

10, 25, 50 are the composite factors of the composite number 50. 2 and 5 are prime.

To determine which number is a prime or composite number, your number must only have two factors, the number itself and one, if it more then two factors then it is a composite number.

Factor it. If you find more than two factors, it's composite.

Yes

It is a prime.

A number can be factored to determine whether it is prime or composite. A prime number has exactly 2 factors, 1 and the number itself. A composite number has more than two factors.

There is no simple answer. You need to check for divisibility by every number from 2 up to its square root. There are some simple rules for checking for divisibility by small numbers. As soon as you have found one such factor you know that it is a composite number.The fact that it is so difficult to tell is why composite numbers made up of two large primes are used for data encryption.

295 is composite - 5 x 59.

If the number can be multiplied by any number other than 1 it is a composite any other is prime

Divisibility is what a number can be divided by.

A divisibility rule is a statement of procedures to determine divisibility. For example:"A number is divisible by 2 if it ends with 0, 2, 4, 6 or 8".It does not make any sense to divide such a sentence by 2 or 895 or any other number!

for any composite number ... check only the highest power of prime factors divisibility .... i guess that will do the work for example ... 400 = 2^4 * 5^2 so you need to check the divisibility by 25 as well as 16 hope this will meet your need

Both numbers are composite numbers. Using the rules of divisibility, 2312 is composite because it is an even number that ends with 0, 2, 4, 6, or 8. 3819 is composite because the sum of its digits equal 21, a number that is divisible by 3, so the number itself is divisible by 3.
