How do you find the LCM using prime factorization?

Find the LCM using the prime factors method

  1. Find the prime factorization of each number.
  2. Write each number as a product of primes, matching primes vertically when possible.
  3. Bring down the primes in each column.
  4. Multiply the factors to get the LCM.

What is the LCM of 8 and 18 using prime factorization?

72
LCM of 8 and 18 by Prime Factorization LCM of 8 and 18 can be obtained by multiplying prime factors raised to their respective highest power, i.e. 23 × 32 = 72. Hence, the LCM of 8 and 18 by prime factorization is 72.

How to find lcm by Division and prime factorization?

LCM By Division method: In this method divide the given numbers by common prime number until the remainder is a prime number or one. LCM will be the product obtained by multiplying all divisors and remaining prime numbers.

How to calculate the LCM of two numbers?

In addition to the cake method, we can calculate the LCM of two numbers by using prime factorization. Once we find the prime factorization of the given numbers by using the factorization tree or the upside-down division method, we mark the common prime factors.

Is the LCM of 24 and 30 equal to all prime factors?

Provided that the common prime factors ( 2 and 3) appear in the multiplication only once, the LCM of 24 and 30 is equal to the product of all prime factors. In addition to the cake method, we can calculate the LCM of two numbers by using prime factorization.
