How do you use the prime factorizations to find the LCM of a and b?
a and b have no common prime factors. Their LCM is their product.
How are gcf LCM and prime factorization related?
You can find the GCF and/or the LCM of a set of numbers by comparing the prime factorizations of the individual members of the set.

What is the first step in finding LCM of tow or more numbers?
Writing the numbers down. If you've already done that, then find their prime factorizations.
What is the LCM of 35 and 50 using prime factorizations.?
5 x 7 = 35 2 x 5 x 5 = 50 2 x 5 x 5 x 7 = 350, the LCM
What is the LCM of 8 and 28?
The LCM is 56 which is 28 x2.If we write the prime factorizations of the two numbers we have:28=22 x78=23Now to find the LCM we multiply 23 x71 =56.56.
How can you determine from the prime factorization whether the least common multiple of two numbers is the product of the numbers?
If the prime factorizations have no factors in common, the LCM is the product of them.
What is a disadvantage of using the prime factorization method to find the LCM?
speed you can just use your brain to find the LCM faster, sometimes.
What is the second step of finding LCM?
If the first step is writing down the numbers, the second step is finding their prime factorizations.
