Book a Free Trial Class. A prime number is a number that has exactly two factors 1 and the number itself. Prime factorization of any number can be calculated out by following two methods:. Prime factorization is the way of writing a number as the multiple of their prime factors.

The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, and so on. The prime factorization of 72, 36, and 45 are shown below. The least common multiple of a number is the smallest number that is the product of two or more numbers. LCM of two numbers can be found out by first finding out the prime factors of the numbers. Then the LCM is the product of the greatest power of each common prime factor.

HCF of two numbers can be found out by first finding out the prime factors of the numbers. Then the HCF is the highest common factor from the prime factors of the two numbers.

FAQs on Prime Factorization. What is Prime Factorization in Math? How to Find Prime Factorization? Prime factorization of any number can be calculated out by following two methods: Method 1: Division method. Method 2: Factor tree method. Factoring is a way to break a number down by finding smaller numbers that can be multiplied together to get that number.

Prime Numbers are numbers that only have two factors, one and itself i. When we are asked to find the prime factorization of a number we are being asked to break a composite number down into only prime numbers.

This is done by finding a factor pair of the given composite number and then factoring that factor pair until we are left with only prime numbers. I like to use a visual called a factor tree to help me find all of the prime factors of a number. Below, I used a factor tree to find the prime factorization of At the top of the tree is the number we are given, in this case Next, we find a factor pair.

I chose to use 6 and 6. Since six is composite, we must find the factors of six. The next factor pair is 2 and 3. Since both 2 and 3 are prime, we can not factor anymore. Thus, the prime factors of 36 are 2,2,3,3. We can check if we have the correct prime factorization by multiplying all of the prime factors together; if the product is the original number then you are done and you found all of the prime factors.

Pre-Algebra Factoring into Primes. Explanations 3 Alex Federspiel. Video Prime Factorization by mathman This video by mathman covers prime factorization. Summary A prime is a number with only two distinct factors: 1 and itself. A composite is a number with more than two distinct factors. The number 1 is a special case.
