Best Answer

The factor tree finds the prime factorization. The prime factorization finds the LCM.

Example: 30 and 42

Factor them.







2 x 3 x 5 = 30

2 x 3 x 7 = 42

Select the highest amount of each factor.

2 x 3 x 5 x 7 = 210, the LCM

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What is the LCM of 12 6 and 3?

The LCM is: 12 to find the LCM you can make a factor tree of each number and after you did that you find a number that all the factor trees have in common and write that number once and if there is more than one number in common with all of the factor trees also write that number down once the rest of the numbers are extras so you want to write those done too then you multiply all the numbers written down and you get the LCM
