When is the LCM of 2 numbers equal to the product of the 2 numbers?
When the two numbers are relatively prime.
How do you find the LCM of 2 numbers if one number is prime?
If the second number is a multiple of the prime number, than the LCM is the second number. If the second number is not a multiple of the prime number, then the two numbers are relatively prime, and the LCM is the product of the two numbers.
What is the LCM for 5 and 8?
40 is the LCM of 5 and 8. If two numbers are relatively prime ( have no divisors in common, the LCM is just their product. )
Is prime factorization always useful in finding LCM?
Most of the time. If you can recognize that the two numbers are relatively prime, factorization isn't necessary. Just multiply the two numbers together.
How do you find the lcm of three numbers when all of them are prime?
When all of them are prime numbers,then just multiply the numbers to get the LCM of those 3 numbers.
Numbers with the LCM of their product?
Numbers that are relatively prime have their LCM as their product.
What is it called when the product of a pair of numbers is the LCM also?
The numbers are relatively prime, or co-prime.
What two numbers have a LCM that is the product of those two numbers?
Numbers that are relatively prime.
When is the LCM of 2 numbers equal to the prodect of the two numbers?
When the numbers are relatively prime.
What two numbers LCM that is the product of the numbers?
Any two that are relatively prime.
When is the LCM of 2 numbers equal to the product of the 2 numbers?
When the two numbers are relatively prime.
How do you find the LCM of 2 numbers if one number is prime?
If the second number is a multiple of the prime number, than the LCM is the second number. If the second number is not a multiple of the prime number, then the two numbers are relatively prime, and the LCM is the product of the two numbers.
Lcm of 2 11 13?
since these numbers are relatively prime the LCM must be their productSo the LCM is 2x11x13 They MUST be relatively primes since they are primes!
What conditions is the LCM of two composite numbers simply the product of the two numbers?
When the numbers are relatively prime.
If the LCM of two numbers is the product of those numberswhat can you say about the 2 numbers?
They are relatively prime.
Under what conditions is the LCM of two composite numbers simply the product of the two numbers?
When the numbers are relatively prime.
Why is the LCM also the product of a pair?
Sometimes it is, sometimes it isn't. If the two numbers have a GCF of 1, they are co-prime or relatively prime and their LCM will be their product.
