Common factors go into the numbers, the numbers go into common multiples.
On the off chance you are asking for equivalent fractions, they are 2/8 and 3/12.
Finding the GCF will help you when you are trying to reduce fractions.
simplest form
One common application of greatest common factors is to simplify fractions. Note that you don't necessarily need the GREATEST common factor; you can simplify by dividing both numbers by any common factor, and then continue looking for additional factors.
You may have answered your own question. Equivalent fractions have common factors. If they don't have common factors, they aren't equivalent.

Equivalent fractions allow you to rewrite fractions with different denominators so they have a common denominator, which is essential for adding or subtracting them. By converting fractions to equivalent forms, you can easily combine their numerators while keeping the common denominator. This simplifies the process and ensures accuracy in your calculations. Ultimately, working with equivalent fractions streamlines the addition and subtraction of fractions, making it more manageable.
You first convert them to equivalent fractions with a common denominator. Or you convert them to decimal fractions.
When a fraction is simplified, it is made into an equivalent fraction with no common divisor between the numerator and denominator.
Fractions don't have common factors. The common factors of 4 and 6 are 1 and 2.
Convert unlike fractions to equivalent fractions with common denominators by finding the LCM of the denominators.
You look for a common denominator; convert the fractions to equivalent fractions with the denominator you found; then you do the addition itself.
Multiply them by each other.
The three types of fractions are: common, improper or 'top heavy' and equivalent fractions
