How to find the LCM using prime factorization?
Steps on How to Find the LCM using Prime Factorization. Step 1: Perform the prime factorization of each number then write it in exponential form. Align the common prime factor base whenever possible. Step 2: For the numbers with a common prime factor base, select the prime number that has the highest power.
Which is the least common prime factor of 24 and 15?
Step 1: Divide the given numbers by the least common prime factor. Here, 3 is the least common prime factor of 24 and 15. Step 2: Continue still there is no more common prime factor. Then multiply all the divisor. Division of 24 and 15 by 3 will leave 8 and 5 as remainders respectively. 8 and 5 do not have a common prime factor.
