Answer 2

Answer:

9072 is the number.

Step-by-step explanation:

We find LCM not HCF because :

The HCF of two or more numbers is the largest common factor of the given numbers. It is the smallest number which divides the two or more given numbers. The LCM of two or more numbers is the smallest number that is a common multiple of two or more numbers.

And if u don't understand this there is a trick:

HCF is smaller than the given numbers and LCM is larger than given numbers.
