**Find the LCM of the following numbers in which one number is the factor of the ****other.**

**(a) 5, 20 (b) 6, 18 (c) 12, 48 (d) 9, 45****What do you observe in the results obtained?**

**Solution (a)**

5, 20

Therefore, L.C.M

**Solution (b)**

6, 18

Therefore, L.C.M

**Solution (c)**

12, 48

Therefore, L.C.M

**Solution (d)**

9, 45

Therefore, L.C.M

We can note that larger number is equal to the L.C.M if one number is the factor of the other given number.
