You look at the larger number (60) and examine its multiples until you find one that is also a multiple of the smaller number.
In this particular case, we only need examine one multiple of 60.
60 is the lowest common multiple.
(60 * 1 = 60)
(15 * 4 = 60)
The LCM is 60.
LCM of 15 and 60 = 60
The LCM is 60.
LCM(15, 20, 30) = 60
The LCM of 15 30 and 60 is 60.
The LCM is 60.
The LCM is 240.
The LCM is 300.
The LCM is 420.
You need at least two numbers to find an LCM. If that's 4 and 15, the LCM is 60.
Two or more numbers are normally needed to find the LCM
Use the LCM for their coefficients.Use each vriable with the LARGEST exponent in each term.Ex: Find the LCM of 15 x2y5 and 20 x3y4LCM of 15 and 20 is 60, LCM of x2 and 20 x3 is x3 , LCM of y5 and y4 is y5So the LCM is 60 x3y5
