Detailed Solution

When the 2 numbers have no common factor then the numbers are called co – primes.
Now, the least common multiple (LCM) of two number say a, b is the smallest positive integer which can be divisible by both the numbers a and b.
Now for 2 co – primes which do not have common factors, the LCM of these numbers must be divisible by both the numbers.
Hence, the lowest common multiple of two co-prime numbers,
LCM (co - primes) = product of those co – primes.
Hence option 3 is the correct answer.
