They are: 3*7*11 = 231
3 x 7 x 11 = 231
To determine factors of a number it is necessary to divide the number by prime numbers of increasing value. If there is no remainder then the prime number is a factor. The square root of 231 is approximately 15 so it is necessary to divide by all the prime numbers up to 13 (15 is not a prime number). 231 ÷ 2 leaves a remainder of 1 231 ÷ 3 divides exactly 77 times (which is 7 x 11 - both are prime numbers) 231 ÷ 5 leaves a remainder of 1 231 ÷ 7 divides exactly 33 times (which is 3 x 11 - both are prime numbers) 231 ÷ 11 divides exactly 21 times (which is 3 x 7 - both are prime numbers) 231 ÷ 13 leaves a remainder of 10 If we multiply together the three numbers that are shown to be factors 3 x 7 x 11 = 231 this confirms that there are no other factors of 231 except 1 and 231 itself. This last condition is true for every positive integer. 231 is divisible by 1, 3, 7, 11 and 231
38 = 2 x 19
As a product of its prime factors: 2*3*7 = 42
They are: 1 times 107 = 107 which is also a prime number
168 = 2 * 2 * 2 * 3 * 7
They are only: 1 times 2003 = 2003 because it is a prime number
3 x 3 x 11
No. Prime factors are the numbers that make up other numbers, but they have to be prime. Prime factorisation is the process of finding the prime numbers that create a number. This is when you multiply the prime numbers together and the product is the original number. For example: 20 5x4 5x2x2 This process is called prime factorisation. In this case, the prime numbers are 2, 2, and 5.
A prime number is prime because It can only be multiplied by 1 and itself which makes it prime. A number is composite because it can be multiplied by more than two factors. factors: Two numbers you multiply together to come up with a number/answer.
Prime numbers are infinite.
No two (or more) composite numbers can multiply to 30.

Yes, in fact, there is no last prime number - the set of prime numbers is infinite. The proof was already known 2000 years ago: If you assume that there is a last prime number, multiply all prime numbers up to that "last prime number". Then add one. The result is either a prime number itself, or it is composed of factors, none of which is one of the prime numbers you multiplied (because of the added 1). Thus, the original assumption (that there is a last prime number) has to be false. Example: The first 3 prime numbers are 2, 3, 5. If you multiply them, you get 30. Add one to the result, and you get 31. This number isn't divisible by 2, by 3, nor by 5. It happens to be a prime, but this isn't always so.
All of the prime numbers up to 10000 can be prime factors.
There is an infinite number of prime numbers after 500!
83, 3,and 2 are prime numbers which add up to 88.
53 and 3 are two prime numbers that add up to 56
127 prime numbers in that range. See related link for prime numbers up to 10000. Plus there is a link to download Zip files of prime numbers up to 1 million.
if you mean what three prime numbers add up to a prime number then the answer is : 5 + 7 + 11 = 23
