Answer:
LCD is the abbreviation for Least Common Denominator.
Explanation:
To find the LCD of two numbers, you list out the multiples of each number. Then you look for the smallest multiple of both numbers and there you have it!
For example, if we had to find the LCD of 4 and 3, we'll first list out the multiples of both.
4: 4, 8, 12, 16, 20, ...
3: 3, 6, 9, 12, 15, ...
The first least multiple we found in those two numbers is 12.
Therefore, the LCD would be 12.
