What is the LCM of 12 3 and 5?
1, and only 1. There are no common factors (whole numbers) between those three numbers but one.
What is the LCM of two that have no common factors greater than 1?
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
Why do some numbers have their LCM and their product the same?
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.
25 is the LCM of what 2 numbers?
The answer is 5 & 25, if you do not include 1 (because its not supposed to be)
What is the least common multiple of 2 feet and 1 yard?
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.
What pair of numbers is the LCM of 5?
1 and 5 have an LCM of 5.
What is the LCM of numbers 1-10?
11
What is the LCM of 12 3 and 5?
1, and only 1. There are no common factors (whole numbers) between those three numbers but one.
Why is 7 and 15 multiplied to get the LCM?
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.
What is the least common multiple of 5 and 9?
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
What is the LCM of 5 only?
You need at least two numbers to find an LCM.
What is the LCM of two that have no common factors greater than 1?
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
What numbers have the same LCM as 12105?
2421 and 5 1345 and 9 269 and 45 all have an LCM of 12105
What are two numbers whose GCF is 1 and LCM is 55?
11 and 5
What are the common multiples of 1 and 3 and 5?
The LCM of the given numbers is 15
Why do some numbers have their LCM and their product the same?
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.
What is the LCM of 11and 2 and 5?
110 because they are all prime numbers
