Did you carefully read all the information in the web site he posted?
If a number is prime then you know that it's a multiple of itself and the number 1.
Example: Multiples for 7 are 7 & 1
Example: Multiples for 23 are 23 and 1
If you wanted to find the the LCM of both it would have to be 23 x 7
Do you understand why? There is no number other than 1 that can divide into both.
If you had non-prime numbers like 4 and 2, their LCM would be 4 since 2x2=4 and 1x4=4.
I don't know if I'm doing a good job explaining this or if I'm confusing you more but I tried.
The multiples of 7 are not 7 and 1, rather what I meant to say is that 1x7 =7, the multiples of 7 would be 7,14,21 ect. Sorry if that confused you. Same with the number 23.
The factors for 7 are 1 and 7
The factors for 23 are 1 and 23
"Since they have no common prime factors between them other than one, the Least Common Multiple must contain all the prime factors of both, making it the product of the two numbers."
This is what drwls posted, and to me it is crystal clear... unless you did not read what he wrote, just scanning for numbers.
