1, and only 1. There are no common factors (whole numbers) between those three numbers but one.
If there is no common factor greater than 1, then the lcm of those numbers is the product of those numbers. eg hcf(5, 7) = 1 → lcm(5, 7) = 5 x 7 = 35 eg hcf(4, 9) = 1 → lcm(4, 9) = 4 x 9 = 36
If the two numbers do not have any factors in common (other than 1), then the LCM is the same as the product of the two numbers. Example: LCM of 5 & 6 is 30, which is the same as the product.
The answer is 5 & 25, if you do not include 1 (because its not supposed to be)
We use the LCM to compare whole numbers. What you do with the numbers after that is your business. 1 yard is 3 feet. The LCM of 2 and 3 is 6.
1 and 5 have an LCM of 5.

1, and only 1. There are no common factors (whole numbers) between those three numbers but one.
The factors of 15 is 3 and 5 i.e we get 15 by multiplying 3 and 5. All the three numbers are prime numbers ( they are divisible by only 1 and themselves). Hence the LCM can be only the product of 3, 5 and 7.
The LCM of 5 and 9 is 45. The LCM is the product of all numbers divided by their highest common factor. 5 is prime, and 9 = 3 x 3 x 1, so the GCF is 1. Thus, the LCM is 5 x 9 = 45.45
You need at least two numbers to find an LCM.
If there is no common factor greater than 1, then the lcm of those numbers is the product of those numbers. eg hcf(5, 7) = 1 → lcm(5, 7) = 5 x 7 = 35 eg hcf(4, 9) = 1 → lcm(4, 9) = 4 x 9 = 36
2421 and 5 1345 and 9 269 and 45 all have an LCM of 12105
11 and 5
The LCM of the given numbers is 15
If the two numbers do not have any factors in common (other than 1), then the LCM is the same as the product of the two numbers. Example: LCM of 5 & 6 is 30, which is the same as the product.
110 because they are all prime numbers
