When is it useful to find the least common multiple and greatest common factor of two or more numbers to solve a problem?
When you are simplifying fractions or adding and subtracting unlike fractions.
What is the greatest common factor of 4862?
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 of 275?
"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.
Why is finding the greatest common factor is useful for fractions?
It allows you to add and subtract the fractions with greater ease.
Greatest Common factor of 24 And 40?
Answer: GCD=8 / LCM=120 A useful link for a GCD/LCM calculator is given below in the related links section.
What is the least common factor of 16 18?
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 would it be useful to know the common factors or the greatest common factor of two or more numbers?
When you need to reduce fractions to their simplest form.
What is the greatest common factor of 126 and 324?
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.
Is it ever useful to know the greatest common factor of 3 or more numbers?
Yes, actually you might use it in tests for school.But its a great use.Trust me!! =)
Why is it important to know how to determine the greatest common factor?
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.
What is use of least common factor?
It's not useful. The least common factor is always 1.
What is the greatest common factor of 7 and 8 and 10?
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.
