What is the greatest common factor of 8and24?
Since 8 is a factor of 24, it is automatically the GCF of this problem.
How do you solve a factoring polynomials problem if there is no greatest common factor?
If there is no common factor then the polynomial cannot be factorised. If there is no common factor then the polynomial cannot be factorised. If there is no common factor then the polynomial cannot be factorised. If there is no common factor then the polynomial cannot be factorised.
How do you get the greatest common factor on a math problem?
By finding the factors in both numbers and then finding the one that is greatest in common. For example the G.C.F for 45 and 36 is 9.
What is the greatest common factor for 14 and 45?
The Greatest Common Factor (GCF) is: 1
What is the greatest common factor of 240 and 42?
The Greatest Common Factor (GCF) is: 6
How do you know whether to use the greatest common factor or the least common multiple to solve a problem?
the least common multiple is what the numbers you are using divide into. e.g. 3 and 6 have 12 as the common factor. the greatest common factor is what divides into your numbers. 6 and 9 have 3 as the greatest common factor
How do you solve a greatest common factor math problem?
21 and 84
Why is it not good to divide the denominator by the greatest common factor?
in what kind of problem?
What is the greatest common factor of 8and24?
