7 and 17
Any pair of prime numbers. 5 and 7 11 and 13
No. You can only find the LCM of at least two numbers, prime or otherwise. The LCM of any two prime numbers is their product.
How about: 4 and 5
30 and 60
There aren't two prime numbers whose LCM is 90.There aren't two prime numbers whose total is 23.Other than that...The two numbers you are looking for are 5 and 18, but only one of them is prime.
3 and 17
7 and 17
13 and 3
The LCM of 60 and 18 is 180
This question feels incomplete, but as written the LCM is 2.
When the numbers are co-prime, ie have no common factor. Simplest example is 2 & 3 whose LCM is 6
Any pair of prime numbers. 5 and 7 11 and 13
The LCM of a set of prime numbers is their product.
When two numbers are relatively prime, the LCM will be their product.
No. You can only find the LCM of at least two numbers, prime or otherwise. The LCM of any two prime numbers is their product.
Numbers that are relatively prime have their LCM as their product.
