Draw a conclusion is the statment below always, sometimes, or never true ? Bive at least two examples to support your reasoning.
lions [1.4K]

Answer:

Sometimes

Step-by-step explanation:

Example 1:

Take two numbers as 7,8

LCM of 7,8=7(8)=56

In this case, the lcm of two numbers is equal to the product of the two numbers.

Example 2:

Take two numbers as 6,3

6=3(2)

So,

LCM of 6,3=3(2)=6

In this case, the lcm of two numbers is not equal to the product of the two numbers.

Therefore,

Sometimes, the lcm of two numbers is equal to the product of the two numbers.
