The LCM of 30 and 42 is 210, a multiple of 7.
The least common multiple of 68 is 2. if u what to divide the number than the least common denominator will be 4.
To find the least common multiple than multiply by a whole number fraction
No.
Never.

The lowest common multiple (higher than 0) is 12. However, any multiple of 12 is a common multiple of 4 and 6.
That's true.
In the set of common multiples, one of them will be smaller than the rest. That's the LCM.
No.
The least common multiple (LCM) of two or more numbers is the smallest number that is a multiple of each of the numbers in the set. For sets of multiples, the LCM is the smallest number that is a multiple of all the numbers in the sets. The LCM can be calculated by finding the prime factorization of each number and then taking the highest power of each prime factor that appears in any of the numbers.
The LCM of 7 and 9 is their product. There is no common multiple that is smaller.
It can't be a factor, common or otherwise, because factors can't be larger than the numbers they supposedly come from. 3360 is a multiple of 16 and 30, but it can't be a common multiple in this problem because it is not a multiple of 36.
