1. First multiply all numbers up from 2.
2. See how many numbers product is 5.
3. If is more than two numbers that's product is five that's a composite number.
4. Is the number only has to products that is five its a prime number.
To prove whether a number is composite, factor it. A number having any factor besides 1 and itself is composite.
If it has more than two factors.
1. Is 10 a composite number?2. Is 3 a composite number?3. Is 17 a composite number?4. Is 24 a composite number?5. Is 31 a composite number?6. Is 38 a composite number?
A number between 1 and 500 is composite if it can be divided, without remainder, by a number other than 1 and itself.
A composite number is when it can be divided evenly by numbers other than 1 or itself. A prime number can be divided, without a remainder, only by itself and by 1. Therefore, zero is neither a composite, nor a primary number.
If it is 5 it is a prime. If it is any other positive integer ending in 5 it is a composite.
To prove whether a number is composite, factor it. A number having any factor besides 1 and itself is composite.
20 is a composite number
Now.... That depends on whether it is a number orr not!? :)
A composite number is an natural number that can be divided, without 27 29
Since 74 is an even number, it can be divided by 2 without getting a remainder. Therefore, it is a composite number.
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.
However by looking at a number it is not easy to figure out whether a number is prime or composite. Every even number excpet 2 is a composite number so, any number having last digit as 0, 2, 4, 6 or 8 is a composite number. This is one of the ways to figure out. However for the odd numbers it becomes diificult to figure out. For a quicker analysis there are divisiblity rules. These are shorthand ways to find whether a number is divisble by another without performing actual division. Please take a look at the related links(below) for more information.

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.

35 is a composite number because it has more than two factors
