You need to know the least common denominator (LCD) of 4 and 37 if you want to add or subtract two fractions with 4 and 37 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 4 and 37 is 148.
Here is a math problem example where you need to know the LCD of 4 and 37 to solve:
3/4 + 2/37 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
148/4 = 37
148/37 = 4
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 37 = 111
2 x 4 = 8
Step 3) Put it all together to solve the problem:
111/148 + 8/148 = 119/148
= 3/4 + 2/37 = 119/148
It's that easy! Once again, the lowest common denominator (LCD) of 4 and 37 is as follows:
148
