Assuming those are denominators of fractions you wish to add or subtract, you can use any common multiple of 4 and 14; the Lowest Common Multiple (LCM), often called the Lowest Common Denominator (LCD) especially when when referring to the denominators of fraction, provides the smallest numerators. For 4 and 14, the LCM is 28.
Find the LCM of the denominators. Since the LCM of 3 and 4 is 12, the least common denominator of 1/3 and 1/4 is 12.
To add two fractions with different denominators, you first need to find a common denominator. In this case, the least common multiple of 7 and 14 is 14. So, you need to rewrite 2/7 as an equivalent fraction with a denominator of 14, which is 4/14. Then, you can add 4/14 + 5/14 to get 9/14 as the sum.

No, you do not need to find a common denominator when multiplying fractions. To multiply fractions, you simply multiply the numerators together and the denominators together. However, finding a common denominator can be helpful when simplifying the resulting fraction.
There are infinitely many common denominators. The least of these is 12.
in order to answer this problem you have to first make the denominators (bottom number) match.Do this by finding the smallest common multiple (the smallest number that both of the denominators divide into) of the denominators.3/4 - 1/23/4 - (1/2) x 2 (4 is the smallest common multiple of 2 and 4. Multiply 1/2 by 2 so that the denominators match)3/4 - 2/4 (now you just subtract the numerators (top number). leave the denominators as they are.)3/4 - 2/4 = 1/4
28 is one what u have to do is find a number that 4 and seven go in to.
The greatest common denominator of any set of denominators is infinite.
3 1 7 4 + 8 is 8. Remember to change the denominators into common denominators. (3/4 would turn into 6/8)
There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of a pair of fractions.
Sometimes fractions have different denominators, like 2/3 and 3/4. If you want to add or subtract them, they need to have the same denominator. In order to do that, you find a common denominator which is the same thing as a common multiple, only with denominators.
