Can two numbers have 16 as their HCF and 380 as their LCM? Give reason. |
|
Answer» No bcoz hcf should be factor of lcm HCF of two numbers is a factor of the LCM of those numbers. Thus, we cannot have two numbers whose HCF is 16 and LCM is 380. Because, when we divide 380 by 16, we get a remainder of 12. Thus, 16 is not a factor of 380. |
