How do you do the LCM by a tree diagram?
Look at both of the numbers' prime factors, and put them into a sum. The LCM multiple is the answer you get from that.
What does the LCM look like?
Example: 30 and 42Factor them.2 x 3 x 5 = 302 x 3 x 7 = 42Combine the factors, eliminating duplicates.2 x 3 x 5 x 7 = 210, the LCM
What is the LCM like of 6 and 21?
42
How do you solve LCM of 24 and 36?
Write out the multiples of each and look for the first overlap. 24, 48, 72 36, 72 The LCM is 72
Why is LCM important?
The LCM is used to convert unlike rational fraction to like fractions so that they can be added or subtracted. Any common multiple will do so the LCM is not that important. However, using the LCM will ensure that the numbers that you have to deal with are as small as they can be.
What are two composite numbers where the LCM is 16?
well, look at the factors of 16...we have 2,4,8, and16.So if we had LCM of 8 and 16, that would be 16 an both are composite
What is the least common multiple of 210 and 45?
630 just look up LCM calculator on the internet
How do you find out the LCM?
To find the LCM you need to skip count the two numbers like: 4,8,12 12,24,36,48 LCM:12 because 4 skip counted to 12 and twelve is the number itself.
What do you do when you have a variable when trying to find the LCM?
The LCM will contain all factors including variables. Look at coefficients and find their LCM. Then IF several terms have a common factor with a differnt exponent, use that variable with the largest exponent. If a variable appears in only one term, it will still be part of the LCM with its exponent. EX Find LCM for 14s3 and 6 ---- ANSWER --- 42s3 Ex Find Lcm for 3x2y , 4y3, and 7x --- The LCM is 84x2y3 biggest exponents even if not in all terms.
What is the LCM of 6and9and12and3?
It is 36 look 36 0n all of them 6,12,18,24,30,36 9,18,27,36 12,24,36 3,6,9,12,15,18,21,24,27,30,33.36
What are the LCM of 40?
There is no answer to that. If you ask for the LCM, you can only apply it to TWO numbers, not one. So you can ask a question like what is the LCM of 40 AND 20 but you can't ask just for one number. It isn't possible.
What is the LCM of 14 what is the LCM of 21 what is the LCM of 35 what is the LCM of 70?
The LCM is: 210
