Is the gcf of all odd numbers always odd and is the gcf of all even numbers always even?
Yes and yes.
Why are GCF and LCM are Almost always never equal?
Because the GCF is the largest factor common to all the numbers in the sample. The LCM is the smallest number that all the sample numbers will divide into !
What is the GCF of each pair of numbers?
The greatest common factor, or GCF, is the largest positive integer that will divide evenly with no remainder into all the members of a given set of numbers. The GCF of 6 and 9 is 3.
What is the GCF of the numbers 141 and 192?
The GCF is 3.
What is the GCF of the numbers 40 and 64?
The GCF is 8.
What is the gcf of all composite numbers under 100?
The GCF of all the composite numbers under 100 is 1. For e.g 4 & 9 are composite numbers & their GCF is 1, so if we take other composite numbers along with 4 & 9 the GCF will be 1.
What two numbers have 1 as there gcf?
Prime and relatively prime numbers all have a GCF of 1.
Is the gcf of all odd numbers always odd and is the gcf of all even numbers always even?
Yes and yes.
What is the GCF of 35 and 8?
The GCF is 1.
What is the gcf of 100 200 140?
The GCF of all three numbers is 20 !
What are all the GCF of 30?
You need at least two numbers to find a GCF.
How can you find a GCF?
Example: GCF of 6 and 12= 2 Example 2: GCF of 54 and 6=9 List all the factors of the numbers you use, then if the numbers you have when you list the factors have the same number in both sets of numbers, that is your GCF
How can you find the gcf of two numbers without knowing the factors?
If one of the numbers is a multiple of the other, the smaller number is the GCF. If the two numbers are prime numbers, the GCF is 1. If the numbers are consecutive, the GCF is 1. If the numbers are consecutive even numbers, the GCF is 2.
What is the greatest common factor of 18 20 and 26?
The GCF of 18, 20, and 26 is 2. The GCF of a set of numbers can't be any larger than the smallest difference between the numbers. The smallest difference within this set of numbers is 2. Since all of the numbers in the set are even, 2 is the greatest common factor.
What is the GCF of 17and 31 and 37?
The GCF is 1.
Why are GCF and LCM are Almost always never equal?
Because the GCF is the largest factor common to all the numbers in the sample. The LCM is the smallest number that all the sample numbers will divide into !
How do you find a pair of numbers when the GCF is given?
To find a pair of numbers with a given GCF, take the GCF number and double it. The pair of numbers is the GCF, and two times the GCF. For instance, two numbers with a GCF of 3 are 3 and 6.
