You need to know the least common denominator (LCD) of 5 and 37 if you want to add or subtract two fractions with 5 and 37 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 5 and 37 is 185.
Here is a math problem example where you need to know the LCD of 5 and 37 to solve:
3/5 + 2/37 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
185/5 = 37
185/37 = 5
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 37 = 111
2 x 5 = 10
Step 3) Put it all together to solve the problem:
111/185 + 10/185 = 121/185
= 3/5 + 2/37 = 121/185
It's that easy! Once again, the lowest common denominator (LCD) of 5 and 37 is as follows:
185
