The Least Common Multiple of 3 and 5 is 15, which would be the denominator to use for fractions with the denominators 3 and 5.

We use the denominator below the numerator.
Several methods are possible. First, you can just multiply two numbers to get a common denominator, and not worry whether it is the least such common denominator, or not. To actually get the LCD, use one of the following methods: (1) Take consecutive multiples of the largest number and see which of them is divisible by the other one. (2) Use prime factorization. (3) Use Euclid's algorithm. This one is the most efficient method for larger numbers.
The least common denominator refers to integers, not decimals. If you convert that 8.5 to 17ths, you could use 476ths.
The Least Common Multiple of 3 and 5 is 15, which would be the denominator to use for fractions with the denominators 3 and 5.
The same process is used to find both. The only difference is the function of the numbers. When we're talking about fractions, we use the term least common denominator.

When adding or subtracting unlike fractions, the LCM process is used to find the least common denominator.

we had to do math that is denominator
When adding two fractions, you want to make sure they have the same (common) denominator. You can use any common denominator, but it's best to use the lowest (least) one so you won't have to reduce it later. Add 1/2 and 1/3. The lowest number that 2 and 3 can both go into evenly is 6, so in this case 6 is the least common denominator.
The factor tree finds the prime factorization of a given number. Combining the prime factorizations of two denominators correctly will give you their least common denominator.
Least common denominator. Used in fractions. For example : 1/2 and 3/4 The fraction that has the lowest denominator, while still having an equivalent fraction is the LCD. In this case it would be 2/4 and 3/4. Because 1/2 = 2/4, and the lowest common denominator between the two fractions is 4. Hope this helps ! :D
