Composite.

Composite.

A prime number, since nothing can add up to it.It has no factors other than itself and one.

If you add the digits together, you get 12. Since 12 is divisible by 3, 327 is also divisible by 3.

Not necessarily. For example 15 and 16 are composite numbers. They add to 31, which is a prime number. Similarly, the composite numbers 20 and 21 add up to 41, which is a prime number.

267 is a composite number - since the digits of the number add up to a multiple of three, it is divisible by 3. Its prime factorization is 3 x 89 = 267.

201 is a composite number because it has more than two factors. If the digits of a number add up to a multiple of three, then the number itself is a multiple of 3. 2+0+1=3, so 201 is divisible by 3 and therefore composite.

Answer:417 is not a prime number. It is a composite number.Definition:A prime number has exactly two factors: 1 (also known as unity) and itself. A composite number has more than two factors; in other words, it has at least one factor besides 1 and itself.Explanation:Any number for which the digits add to a number divisible by 3 is also divisible by 3, so it has 3 as a factor. The sum of the digits of 417 is 4 + 1 + 7 = 12, which is divisible by 3. Thus, 417 is also divisible by 3, so it is a composite number.417 is a composite number. 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.

Yes it is, the numbers that can add up to 4 are 1, 2 and 4. A prime number is a number that can only go to itself and 1 evenly, composite have atleast 1 other number that goes into it perfectly. (that's what she said)

You may mean: 3 and 5 are prime numbers that add up to the composite number of 8

57 divided by 3 is 19. (Any number in which all the digits add up to equal a number divisible by 3 is divisible by 3. 5+7=12 which is divisible by 3.) And since 57 is divisible by more numbers than just 1 and itself it is a composite number.

Composite: 651 has 3 as one of its factors (add the digits 6+5+1=12, which is a multiple of 3).Since it has a factor (3) in addition to itself and 1, it is composite.

Any number whose digits add up to 9 or a multiple of 9 is divisible by 9. Since the numbers' digits also add up to a multiple of 3, 441 is also divisible by 3.A complete list of all of the positive integer factors of the number is:1, 3, 7, 9, 21, 49, 63, 147, 441441 is a composite number. 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.

composite. 57 divided by 3 is 19. (Any number in which all the digits add up to equal a number divisible by 3 is divisible by 3. 5+7=12 which is divisible by 3.) And since 57 is divisible by more numbers than just 1 and itself it is a composite number.57 is a composite number since it can be divided by 3.57/3 = 19Composite.

Answer:6003 is not a prime number. It is a composite number.Definition:A prime number has exactly two factors: 1 (also known as unity) and itself. A composite number has more than two factors; in other words, it has at least one factor besides 1 and itself.Explanation:Any number for which the digits add to a number divisible by 3 is also divisible by 3, so it also has 3 as a factor. The sum of the digits of 6003 is 6 + 0 + 0 + 3 = 9, which is divisible by 3, which means 6003 is divisible by 3. Therefore, 6003 is a composite number.

337890 is a composite number. It is an even number greater than 2, ends with a zero and the sum of its digits add up to a number that is divisible by 3, so it is divisible by 2, 3 and 10 in addition to itself and 1.

The first two prime numbers add up to another prime number.

The digits of 291 add to 12 which is divisible by 3. So 291 is divisible by 3 so it cannot be prime.

By definition, 1 is not prime. A prime number has exactly two unique natural number divisors; itself and one. You can understand '1 and 1' to be two numbers, but they are not unique. The same reasoning brings us to the conclusion that 1 is not composite; a composite number can be divided without remainder by at least one integer other than itself and 1.

As long as 2 is not one of the primes that you are adding, then I can guarantee that you will get a composite. 2 is the only even prime number. Any time you add two odd numbers together, you will get an even number (which is not prime). So if you add them in pairs, you will have three even numbers, which added together result in an even number, so it is composite. If you throw in 2 as one of the primes that you're adding, then your result is odd, and I don't know what else to say about your result.

57 divided by 3 is 19. (Any number in which all the digits add up to equal a number divisible by 3 is divisible by 3. 5+7=12 which is divisible by 3.) And since 57 is divisible by more numbers than just 1 and itself it is a composite number.

The only number between 30 and 40 with distinct prime factors which add up to 12 is 35.
