Find the GCF when you want to simplify a fraction.
Find an LCM when you want to add and subtract fractions.
When you are simplifying fractions or adding and subtracting unlike fractions.
4862 has no common factor. It has nothing to be common with. Inaccurately worded questions make it difficult for answerers to give useful information.
"Greatest common factor" and "least common multiple" only give useful information for more than one number. The greatest common factor of any number would be the same number - in this case, 275.
It allows you to add and subtract the fractions with greater ease.
Answer: GCD=8 / LCM=120 A useful link for a GCD/LCM calculator is given below in the related links section.
The least common factor of any two (or more) whole numbers is 1. Please note that there is no useful reason to get such a least common factor. Usually you'll want the GREATEST common factor, or the LEAST COMMON MULTIPLE of two or more numbers.
When you need to reduce fractions to their simplest form.
The least common factor is a term often mistakenly given to either the greatest common factor (GCF) or the least common multiple (LCM). This term is not often used because it does not describe a useful relationship between numbers. Since 1 evenly divides all integers, 1 is technically the least common factor for any set of integers.The smallest non-one common factor of 192 and 1296 is 2.
Yes, actually you might use it in tests for school.But its a great use.Trust me!! =)
It's not useful. The least common factor is always 1.
It help factor your answers for the future. Especially when you use factoring, quadratic formula and the like. It's very useful when you reach Freshman Algebra.
Technically, 7 is a prime number so itself and 1 are the only candidates. If you consider 1 to be a factor, then the only common factor is 1, which is not useful in any application I know.
