What is the LCM of 6 4 and 2?
The LCM is 12.
When can the LCM of two numbers be one of those numbers?
The LCM of 2 numbers can be one of those numbers when the large of the 2 numbers is 2 times the smaller one of those numbers. For example the LCM of 2 and 4 is 4. For example the LCM of 5 and 10 is 10.
What is the LCM of 2 4 7 and 14?
To find the LCM of a set of numbers, you first need to work out their prime factors: 2=2 4=2x2 7=7 14=2x7 The next step is to identify any common factors. Three numbers have a 2, so two of these can be discarded. Also, two numbers have a 7, so one of these can be discarded. This leaves us with 2, 2 and 7. To find the LCM we simply multiply these numbers together: 2x2x7 = 28 Thus the LCM of 2, 4, 7 and 14 is 28.
What are two numbers whose LCM is less than their product?
The LCM of 4 and 6 is 12.
How can the LCM be equal to the greatest number in the set?
If the other numbers are all factors of the greatest number, then that number will be the LCM. Example: 2, 4 & 8: both 2 and 4 are factors of 8, so 8 is the LCM. 2, 3 and 12: same thing, both 2 & 3 are factors of 12.
