When adding and subtracting unlike fractions, it is necessary to find a least common denominator. It's the same process as finding an LCM. You can simplify a fraction by finding the GCF of the numerator and denominator and dividing them both by it.

You cannot compare fractions by using the GCF since GCF determines the common factors of both fractions. Instead, use the LCD to compare the fractions. Find the LCM of the denominator terms of the fractions. Then, obtain the fractions with the common denominators. Finally, compare the numerator values to determine which fraction is the greatest/least.

Example: 30/42

The GCF of 30 and 42 is 6.

Divide them both by it.

30/42 reduces to 5/7

Example: 30/42
If you know that the GCF of 30 and 42 is 6, you can divide both of those numbers by 6 and get 5/7.

Divide both the numerator and the denominator by their GCF. The result will be the simplest form of the fraction. If the GCF is 1, the fraction is already in its simplest form.
