**How to Find Common Denominators Quick and Dirty Tips**

For the first fraction, your denominator is already your common denominator, so you simply multiply it by 1/1. We multiply by 1 (or a fraction equaling one) because this does not change the amount of the fraction, it just changes the name of the fraction. For the second fraction, you would multiply by 2/2 because your denominator (2) needs to be multiplied by 2 to reach the common denominator... The least common multiple (LCM) is the lowest (least) postive number that two or more numbers can be divided into without a remainder. To find it, you can list the multiples, in order, of the given numbers.

**What is the Least Common Denominator of 20 and 45?**

For the first fraction, your denominator is already your common denominator, so you simply multiply it by 1/1. We multiply by 1 (or a fraction equaling one) because this does not change the amount of the fraction, it just changes the name of the fraction. For the second fraction, you would multiply by 2/2 because your denominator (2) needs to be multiplied by 2 to reach the common denominator... The greatest common factor is the largest factor that divides two numbers. We find this by figuring out what prime numbers are multiplied together to make up each number. A prime number is a number that can only be divided by itself or by one. Examples of prime numbers are 1, 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, etc. We want to focus on those that are less than ten in most cases.

## How To Work Out Lowest Common Denominator

### In working with fractions, you always want to simplify your answer to its lowest term by dividing both the numerator and denominator by the greatest common factor they share. In the example 4/20, 4 and 20 both share the common factor of 4. Divide both the numerator and the denominator by the greatest common factor to find the simplest form of the fraction. Therefore, 4/20 can be simplified to 1/5.

- Then cross out the denominator, divide it by 2 and write the remainder in its place: 3/1. This is called in-problem reducing. It simplifies the denominator of the second fraction to 1, â€¦
