You need to know the least common denominator (LCD) of 59 and 39 if you want to add or subtract two fractions with 59 and 39 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 59 and 39 is 2301.
Here is a math problem example where you need to know the LCD of 59 and 39 to solve:
3/59 + 2/39 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
2301/59 = 39
2301/39 = 59
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 39 = 117
2 x 59 = 118
Step 3) Put it all together to solve the problem:
117/2301 + 118/2301 = 235/2301
= 3/59 + 2/39 = 235/2301
It's that easy! Once again, the lowest common denominator (LCD) of 59 and 39 is as follows:
2301
