Dear student ,
The two numbers which have only 1 as their common factor are called co-primes.

For example,
Factors of5 are1,5
Factors of3are1,3
Common factors is1.
So they are co-prime numbers.

To find their LCM,we

choose each prime number with the greatest power and multiply them to getthe LCM.
=>LCM=3×5=15

Hence, LCM of two co-prime numbers is their product.(a)
