how to find greatest common factor and least common multiple?
167244
One way to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.

To find the greatest common factor of two monomials, first find the prime factorization of each monomial, including all the variables (and a – 1 factor if necessary). Then take the product of all common factors. First, find the prime factorization of each monomial. So, the GCF is 3p2r3 .

Although the numbers in bold are all common factors of both 36 and 54, 18 is the greatest common factor. The second method to find the greatest common factor is to list the prime factors, then multiply the common prime factors.

The least common multiple is the smallest number that has each of the numbers as a factor. The steps he uses for both numbers and variables are: 1. Write the prime factorization of each number (or variable).

To find the greatest common factor (GCF) between monomials, take each monomial and write it's prime factorization. Then, identify the factors common to each monomial and multiply those common factors together. Bam! The GCF!

We can find the greatest common factor of a series of numbers by performing the prime factorization of each number. The greatest common factor will be the product of the combinations of prime factors that each number has in common. 36 can be factorized to 22 * 32.

A common factor of two numbers is a factor that divides both numbers. The greatest common factor (GCF) of two numbers is the greatest number that divides both numbers. To find the GCF, take the prime factorization of both numbers. Then write down the factors that they have in common.

To find the least common multiple (LCM) of a set of monomials, find the LCM of the constants and the LCM of each of the variables. After finding these, multiply them all together to get the LCM of the set of monomials. Example: What is the least common multiple (LCM) of the.

2 Answers By Expert Tutors GCF = lower number. The least common multiple or LCM is the "smallest number" that both numbers will go into. A good working definition after you've listed the multiples (if you have listed them in numerical order), is to stop once you have found a number that is the same in each row.
