Do factor trees always work for determining the greatest common factors?
If you construct them correctly, factor trees always work to determine the prime factorization of a number. Once you compare the prime factorizations of two or more numbers, it is relatively easy to find the greatest common factor of them from there.
What is the least common multiple of 12 8 24 show work?
Multiplying the highest prime factors it is: 72
what is the largest factor that two numbers share is called?
The greatest common factor (GCF) of two (or more) numbers is the greatest factor that divides two numbers. To find the GCF you must work out and list the prime factors of each of the numbers. You will see that the numbers have prime factors in common. Multiply those factors the numbers have in common together and this gives you the GCF for the numbers. eg Number A = 18, Prime factors = 2*3*3 Number B = 24, Prime factors = 2*2*2*3 The Prime factors that A and B have in common are 2 and 3 Multiply them together = 6 6= the GCF of 18 and 24
How do you do the work for the greatest common factor of 65 and 112?
List the factors. 1, 5, 13, 65 1, 2, 4, 7, 8, 14, 16, 28, 56, 112 The only and therefore greatest common factor is 1.
Do a factor tree and factor rainbow?
It's tough to guess what the rest of this question would have been. Factor trees and rainbows are essentially the same thing: ways to notate the process of finding the prime factorization of a given number. With a tree, you write the given number at the top of the page and work down until the lowest branch consists entirely of prime factors and with a rainbow you write the given number at the bottom of the page and work up until the highest arc consists entirely of prime factors. If your original question was going to be, "Do a factor tree and factor rainbow like each other?" I can't help you.
How do you work out the highest common factoer off 126?
Two or more numbers are needed to work out the highest common factor
What is the Highest common factor of 119 and 161?
The highest common factor of 119 and 161 is seven. You have to find all of the numbers factors before you can work it out. the factors of 119 are 1,7,17 and 119, and the factors of 161 are 1,7,23 and 161, therefore the only number that occurs twice in both sequences is 7 so that is the highest common factor
When factorising find the common factor?
To find the common factor when factorising, look for any common factors that can be divided evenly from all the terms in the expression. Divide each term by this common factor, and then factorise the resulting expression further if possible. This will help simplify the expression and make it easier to work with.
How would you work out the common factors of 8 and 16?
Since 8 is a factor of 16, all of its factors are common.
How do you work out ratio of 24 to 15?
The ratio is simply 24/15. That fraction (or ratio) can be simplified by dividing both numbers by their highest common factor.
How do you work out the Highest Common Multiple?
There ain't no such animal! Highest goes with Common FACTORS; LEAST goes with Common Multiples.
What is the greatest common factor of 49 and 153?
That would be 1. The only other factor of 49 is 7, and that doesn't work.
What is 78 divided by 3796 showing work?
0.0205
How do you show work for the common factor for 63 and 72?
1,3,7,9,21,63 1,2,3,4,8,9,18,24,36,72 The factors in common are 1,3,9 The largest (greatest) common factor is 9
How do you work out the lowest common factor of 5 and 6?
The lowest common factor of two or more numbers will always be 1.
What is the greatest common factor of 128 and show the work for the greatest common factor?
You need at least two numbers to find a GCF.
What is the CF Common Factor of 24 and 48 Show your work?
There's no work to show. 24 is a factor of 48, so it has to be the GCF.
