You need to know the least common denominator (LCD) of 56 and 6 if you want to add or subtract two fractions with 56 and 6 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 56 and 6 is 168.
Here is a math problem example where you need to know the LCD of 56 and 6 to solve:
3/56 + 2/6 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
168/56 = 3
168/6 = 28
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 3 = 9
2 x 28 = 56
Step 3) Put it all together to solve the problem:
9/168 + 56/168 = 65/168
= 3/56 + 2/6 = 65/168
It's that easy! Once again, the lowest common denominator (LCD) of 56 and 6 is as follows:
168
