WHAT IS A LESAT COMMON DENOMINTAIR
the least common multiple of two or more denominators. I copied it from merriam webster website. Too hard for me to explain it. this pretty much explains it. a factor is (plz jiskha staff plz make sure im correct) a number that in combination makes up another number by multiplying each other. hope this helps :-)

The term you are looking for is "least common denominator" (LCD). The least common denominator is the smallest number that is divisible by all the denominators in a given set of fractions or rational numbers. It is essential when adding or subtracting fractions with different denominators.
To find the least common denominator, you can follow these steps:
1. Write down the denominators of the fractions you want to find the LCD for.
2. Identify the prime factors of each denominator. Prime factors are the numbers that can only be divided evenly by themselves and 1.
3. Determine the highest number of occurrences for each prime factor across all denominators.
4. Multiply all those prime factors together, including the highest number of occurrences found in step 3. The result will be the least common denominator.
For example, let's find the LCD for the fractions 1/3 and 2/5:
1. The denominators are 3 and 5.
2. The prime factors for 3 are 3 (since it is a prime number).
The prime factors for 5 are 5 (again, since it is a prime number).
3. Both denominators have a single occurrence of each prime factor.
4. Multiply 3 and 5 together, which equals 15.
So, the LCD of 1/3 and 2/5 is 15.
In conclusion, the least common denominator (LCD) is the smallest number that is divisible by all the denominators in a set of fractions or rational numbers. It allows you to add or subtract fractions with different denominators.
