As we always do in these articles, it's worth a very quick recap on fraction terminology. The number above the line is called the numerator and the number about the line is called the denominator. So, in this example, our numerators are 88 and 82, while our denominators are 74 and 97.

What is the Lowest Common Denominator?

To calculate the lowest common denominator, the easiest way is to look at the factors of those numbers and find the lowest common multiple. Here's how that looks for 74 and 97:

• Factors for 74: 1, 2, 37, and 74
• Factors for 97: 1 and 97

Since there are no common factors in 74 and 97, the easiest way to get the lowest common denominator is to multiply them:

74 x 97 = 7178

The next step is to calculate the numerator and complete our fraction. To do this, we need to find the greatest common factor of the numerators, which are 88 and 82.

• Factors for 88: 1, 2, 4, 8, 11, 22, 44, and 88
• Factors for 82: 1, 2, 41, and 82

As we can see, the greatest common factor between the numerators is 2, so this becomes our numerator in the fraction:

We can simplify this fraction down even further and reduce it to the following:
