You need at least two numbers to find an LCM.
If the other number is a multiple of 5, it will be the LCM. If not, the LCM will be their product.
The LCM of 5, 9, and 15 is 45.
5 and 60 have a gcf of 5 and a LCM of 60
It is: 60
That's known as the LCM. The LCM of 2 and 3 is 6. The LCM of 30 and 42 is 210. The LCM of 2 and 5 is 10.
The LCM of 8 and 5 is 40, since that's the smallest number that's a multiple of both 8 and 5.
LCM of a prime number and a composite number is equal to their product if the latter is not divisible by the former. 5 is a prime number and 49 is a composite number. 49 is not divisible by 5. So, LCM(5,49) = 5 x 49 = 245. Actually the reason behind this is that both(5 and 49) do not share any common factors except 1, so the LCM is equal to the product.
5 and 10
If the other number is not a multiple of 5, the LCM is the product of 5 and the other number.
Not always, sometimes the LCM equals the greatest number, i.e.the LCM of 5 and 6 is 30, the LCM of 3 and 6 is 6.
The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question! The least multiple of a number is itself.
