You need to know the least common denominator (LCD) of 58 and 4 if you want to add or subtract two fractions with 58 and 4 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 58 and 4 is 116.
Here is a math problem example where you need to know the LCD of 58 and 4 to solve:
3/58 + 2/4 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
116/58 = 2
116/4 = 29
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 2 = 6
2 x 29 = 58
Step 3) Put it all together to solve the problem:
6/116 + 58/116 = 64/116
= 3/58 + 2/4 = 64/116
It's that easy! Once again, the lowest common denominator (LCD) of 58 and 4 is as follows:
116
