That's an infinite list.

That's an infinite list.

Somewhere in front of you was a list of numbers. The instructions were asking you to break down the numbers and write them as a product of their prime factors. This is known as the prime factorization. The prime factorization of 30 is 2 x 3 x 5.

Every member of that infinite list is different.

A prime factorization is the unique way to list any integer greater than 1 as a product of prime numbers. An example of the prime factorization of a composite number is 20=2*2*5 or 20=2^2*5. The prime factorization of a prime number is itself. e.g. 11=11.

It is a list of prime numbers.

Prime factorization and the Euclidean algorithm

Do you mean what is a list of prime numbers up to 11? If that is the question, the answer is 2, 3, 5, 7, 11. If you're asking for the prime factorization, it doesn't have one. 11 is already prime. The only prime factor of 11 is 11.

do the prime factorization of the 3 numbers. list the prime factors of all the 3 numbers. circle the factors that are common to the 3. multiply them. that number is the HCF

what is the ratio or prime numbers to composite numbers in this list/10,11,2,13,14,15,16,1,7,18,19,20,21

The list of prime numbers is infinite. There are two factors for each.

You can't have prime factorization without having a number to factor.

The list is far too long to list here (millions of them); a search on "list of prime numbers" can quickly give you the desired prime numbers.

Prime factorization is a list of all the primes that multiply to make the original number. Thus to find that number you just multiply all these numbers together. In this case we have 2, 2, 7 and 7, so multiply them together to get: 2x2x7x7 = 296. Therefore, 2x2x7x7 is the prime factorization of 296.

Prime numbers that are next to each other on the list of prime numbers.

All even numbers from 4 upwards are composite numbers and that 2 is the only even prime number.

2 x 3 x 3 x 5The prime factorization simply means a list of all the factors (numbers that multiply together to make the number) that are prime.

Prime factorisation of letters is not defined.

94 = 2 * 47

5 x 7 = 35

Each number is either itself a prime number, or it can be separated into smaller prime numbers. A prime number is a number that has no smaller factors. Factorization into prime factors is unique, except for the order of the factors.

Some of the prime numbers are 2,5,7,3,11,13,19,23....etc.

list the prime numbers between one and twenty

If you use the "list the multiples" method of finding the LCM, it is likely that the lists and the size of the numbers on the list will increase as the numbers you are comparing get larger. If you learn the "prime factorization" method, you can avoid that.

You can list the multiples or use prime factorization.
