What is an example of a LCM word problem?
Find the lowest number which is more by 6 to be divided by 25, 40 and 60 exactly. We find the L.C.M. of 25, 40 and 60. Therefore, the required number is 600 + 6 = 606.
What is the LCM of 40 and 45?
360
The LCM of 40 and 45 is 360.
What is the LCM of 12 and 18?
36
The least common multiple (LCM) of 12 and 18 is 36. LCM stands for the lowest common multiple. Look at the common multiples of 12 and 18 listed on slide number 9. The smallest is 36, so 36 is the LCM of 12 and 18.
