What is the LCM of 1.5 and 5?
LCM of 1.50 and 5.00 is the smallest number which divides both 1.50 and 5.00 exactly without a remainder.
Answer: LCM of 1.50 and 5.00 is 15
Explanation
Least Common Multiple is the smallest number which will divide 1.50 and 5.00 exactly.
LCM of 1.50 and 5.00 by Listing Method
For 1.50 and 5.00, move the decimal 2 places to the right. Now, they are whole numbers. We will find the LCM of 150 and 500. In the end, we will move the decimal point back to 2 places to the left.
- Multiples of 150 are 150, 300, 450, 600, 750, 900, 1050, 1200, 1350, 1500, 1650, 1800, ...
- Multiples of 500 are 500, 1000, 1500, 2000, 2500, ...
The lowest common multiple of 150 and 500 is 1500
So, LCM(150, 500) = 1500
Now, we move the decimal towards 2 places to the left.Therefore LCM(1.50,5.00) = 15.00
LCM of 1.50 and 5.00 by Common Division Method
For each of the numbers we move the decimal to two places to the right and do the calculation of finding the LCM of whole numbers 150 and 500, then in the end we move the decimal to two places back.
We see that LCM of 150 and 500 is1500 Since we multiplied by 100 to remove the decimal point, we will divide by 100, that is, moving the decimal point to two places back. So, we get the LCM of 1.5 and 5 as 15
