Lcm Prime Factorization


Introduction to LCM prime factorization:

Prime factorization is defined as the two factors of number is must be a prime number.

For example:

The prime factorization of the number x is y and z. Then the factors of the number y and z.

Y must be 1 and y similarly the factor of the number z must one and z. In this article we shall discuss about LCM prime factorization with suitable example problems

I like to share this What is LCM with you all through my article.

Example Problem for Lcm Prime Factorization:

LCM prime factorization problem: 1

find the LCM prime factorization for 24, 12.

solution:

Given that 24 and 12. Find the Factors of two numbers individually

Take the 24 and divide through small number.

`24 / 2` = 12

`12 / 2 ` = 6

`6 / 2` = 3

`3 / 3` = 1

24 = 2 * 2 * 2 * 3

`12 / 2` = 6

`6 / 2` = 3

`3 / 3` = 1

12 = 2 x 2 x 3

prime factorization of 24 = 2 x 2 x 2 x 3

prime factorization of 12 = 2 x 2 x 3

LCM of two numner 12 , 24 is 24.

So the LCM prime factorization of 24 and 12 is 2 x 2 x 2 x 3 = 24 .

LCM prime factorization problem: 2

find the LCM prime factorization for45 ,  25.

solution:

Given that 45 and 25. Find the Factors of two numbers individually

Take the 45 and divide into small number.

`45 / 3` = 15

`15 / 3` = 5

`5 / 5 ` = 1

45 = 3 x 3 x 5

`25 / 5` = 5

`5 / 5 ` = 1

25 = 5 x 5

prime factorization of 45 = 3 x 3 x 5

prime factorization of 25 = 5 x 5.

LCM of 45, 25 = 225

So LCM prime factorization of 45 and 25 is 3 x 3 x 5 x 5 = 225

Example Problem for Lcm Prime Factorization:

Find the LCM prime factorization for 54, 50

solution:

Given that 54, 50. Find the Factors of two numbers individually

Take the 54 and divide throughout small number.

`54 / 2` = 27

`27 / 3` = 9

`9 / 3` = 3

`3 / 3` = 1

54 = 2 * 3 * 3 * 3

`50 / 2` = 25

`25 / 5` = 5

`5 / 5` = 1

50 = 2 x 5 x 5

prime factorization of 54 = 2 x 3 x 3 x 3

prime factorization of 50 = 2 x 5 x5

LCm of 54 and 50 = 1350

So LCM prime factorization of 54 and 50 is 2 x 3 x 3 x 3 x 5 x 5 = 1350

Example 4:

find the LCM prime factorization for 96, 18

solution:

Given that 96, 18. Find the Factors of two numbers individually

Take the 96 and divide through small number

`96 / 2` = 48

`48 / 2` = 24

`24 / 2` =12

`12 / 2` = 6

`6 / 2` = 3

`3 / 3 ` = 1

96 = 2 * 2 * 2 * 2 * 2 * 3

`18 / 2` = 9

`9 / 3` = 3

`3 / 3` = 1

18 = 2 x 3 x 3

prime factorization of 96 = 2 x 2 x 2 x 2 x 2 x 3

prime factorization of 18 = 2 x 3 x 3

LCM of 96 and 18 = 268

So LCM prime factorization of  96 and 18 is 2 x 2 x 2 x 2 x 2 x 3 x 3= 288
