You need to know the least common denominator (LCD) of 28 and 37 if you want to add or subtract two fractions with 28 and 37 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 28 and 37 is 1036.
Here is a math problem example where you need to know the LCD of 28 and 37 to solve:
3/28 + 2/37 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
1036/28 = 37
1036/37 = 28
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 37 = 111
2 x 28 = 56
Step 3) Put it all together to solve the problem:
111/1036 + 56/1036 = 167/1036
= 3/28 + 2/37 = 167/1036
It's that easy! Once again, the lowest common denominator (LCD) of 28 and 37 is as follows:
1036
