What is the Least Common Denominator of 1 and 16?
You need to know the least common denominator (LCD) of 1 and 16 if you want to add or subtract two fractions with 1 and 16 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 1 and 16 is 16.
Here is a math problem example where you need to know the LCD of 1 and 16 to solve:
3/1 + 2/16 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
16/1 = 16
16/16 = 1
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 16 = 48
2 x 1 = 2
Step 3) Put it all together to solve the problem:
48/16 + 2/16 = 50/16
= 3/1 + 2/16 = 50/16
It's that easy! Once again, the lowest common denominator (LCD) of 1 and 16 is as follows:
16
