Question 1207612
i must admit i struggled with this, but i found a calculator on the web that told me different ways to find the answer in addition to find the answer for me.


that calculator can be found at <a href = "https://www.calculatorsoup.com/calculators/math/lcm.php" target = "_blank">https://www.calculatorsoup.com/calculators/math/lcm.php</a>


the answer is 4140.
that's the least common multiple.


the calculator gives you the answer PLUS it describes how the answer was derived, using different methods.


for example, i selected GCF method (greatest common factor).


it solved the problem by doing the following:


you are looking for the least common multiple for 36, 90, 345.


first find the greatest common factor for 36, 90.
that turns out to be 18, because 18 is the greatest common factor that divides evenly into 36 and 90.
36 * 90 / 18 = 180.


you now want to find the greatest common factor of 180, 345.
that turns out to be 15, because 15 is the greatest common factor that divides evenly into 180 and 345.
180 * 345 / 15 = 4140.


your least common multiplier is 4140.


try the calculator out for yourself and go through the different methods.
it provides the answer and instructs you on how the answer was derived.


very neat.
