What is the LCM of 7.5, 6, and 5?

To find the LCM of three numbers, we need the least number which is exactly divisible by all the three numbers without leaving any remainder.

Answer: LCM of 7.5, 6, and 5 is 30

The Least Common Multiple (LCM) of 7.5, 6, and 5 is the smallest number which is divisible by 7.5, 6, and 5 exactly.

Explanation:

We are using the listing of multiples method to find the least common multiple of 7.5, 6, and 5.

We will list the first few multiples of 7.5, 6, and 5 and determine the common multiples.

The least among the common multiples is the LCM of 7.5, 6, and 5

• Multiples of 7.5: 7.5, 15, 22.5, 30,...
• Multiples of 6: 6, 12, 18, 24, 30, 36,...
• Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40,...

Here, 30 is the least common multiple of 7.5, 6, and 5. So, the LCM of 7.5, 6, and 5 is 30.

Therefore, LCM of 7.5, 6, and 5 is 30
