- Bdifference
- ✓product
- Dquotient
The two numbers which have only $1$ as their common factor are called co-primes.
For example, Factors of $5$ are $1, 5$
Factors of $3$ are $1, 3$
Common factors is $1.$
So they are co-prime numbers.
To find their $LCM,$ we
then choose each prime number with the greatest power and multiply them to get the $LCM.$
$\Rightarrow LCM = 3 \times 5 = 15$
Hence, $LCM$ of two co-prime numbers is their product.
