It means write down the factors of both numbers. Try 30 and 42.
1, 2, 3, 5, 6, 10, 15, 30
1, 2, 3, 6, 7, 14, 21, 42
Write down the numbers on both lists.
1, 2, 3 and 6 are the common factors. The largest of these is 6. 6 is the GCF.

What is the GCF of 30 and 65?
The gcd or gcf is 5. We could find this by factoring. Another way is to list the factors and then find the biggest common one.
How do you find the GCF of numbers using intersection of sets?
If you were to find the GCF of 20 and 36. Draw 2 overlapping circles. List "20" above one of the circles and "36" above the other. In the circle under "20", list the factors of 20 that are NOT factors of 36- 1, 5, 10, 20. In the other circle, list the factors of 36 that are NOT factors of 20- 1, 3, 6, 9, 12, 36. The factors that 20 and 36 that are in common are listed in the overlapping part of the circle or intersection- 2, 4. The greatest number in common is 4 (GCF). In other words, the largest number listed in the intersection is the GCF.
How do you find out the GCF of 45 60?
First you find the factors of 45 and 60. The Factors of 45 are:1,3,5,9,15,and 45 The Factors of 60 are:1,2,3,4,5,6,10,12,15,20,30,60 The GCF is the highest common number so the GCF is 15.
How do you find the gcf of 15 and 27?
Find out all the factors and then find the greatest common factor (gcf)...........very easy
HOW to find GCF of 25 and 41?
for this problem it is 1. but how you do it is name the factors of 25 then of 41. and whatever one is the highest and in both list is the answer. Good luck
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

What is the GCF of 39 and 65 using list of factors?
It is: 13
What are the factors for the GCF 4?
The factors of 4 are 1, 2 and 4. You need another set of factors to find a GCF.
How do you find out the GCF of 45 60?
First you find the factors of 45 and 60. The Factors of 45 are:1,3,5,9,15,and 45 The Factors of 60 are:1,2,3,4,5,6,10,12,15,20,30,60 The GCF is the highest common number so the GCF is 15.

Find the GCF of 14 52 84?
Factors of 14... 1,2,7,14 - Factors of 52... 1,2,4,13,26,52 - Factors of 84... 1,2,3,4,6,14,21,28,42,84 - Therefore - the GCF is 2 !
What is the product of all common factors in a list of terms?
The product of all the common prime factors is the GCF. The product of all common factors would vary according to the list.
