63 ... 3, 7, 9, 21, 63
36 ... 2, 3, 4, 6, 9, 12, 18, 36
common factors ... 3, 9
It is 12. Beacause the factors of 36 are: 1,36,3,12,4,9,6 and the factors of 84 are: 1,84,7,12 12 is the highest factor that both numbers have in common.
The common prime factors of 18 and 36 are 2 and 3. Both numbers can be divided evenly by 2 and 3.
The numbers that go into both 27 and 36 are their common factors. The factors of 27 are 1, 3, 9, and 27, while the factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. The common factors of 27 and 36 are 1, 3, and 9. The greatest common factor is 9.
they both have some of the same factors of each other
The greatest common factor (GCF) of two numbers is the largest number that divides both numbers evenly. To find the GCF of 36 and 162, you need to determine the common factors of both numbers. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36, while the factors of 162 are 1, 2, 3, 6, 9, 18, 27, 54, and 162. The largest number that appears in both lists is 18, so the GCF of 36 and 162 is 18.
In order to find the common factors of 2 numbers, it is easiest to first list their factors. The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18 and 36 The factors of 24 are: 1, 2, 3, 4, 6, 8, 12 and 24. The common factors are the numbers that appear in both lists. These are 1, 2, 3, 4, 6 and 12.
You search for a common factor, in this case between 36 and 12, and then divide both numbers by this common factor. Repeat, until there are no more common factors.

-- The factors of 20 are 1, 2, 4, 5, 10, and 20. -- The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. -- The (common) factors of both 20 and 36 are 1, 2, and 4 . -- The greatest one of the common factors (GCF) of 20 and 36 is 4 . The answer has got to be somewhere in here.
Look for common factors of the two numbers. Divide both numbers by such a common factor. Continue until there are no more common factors.
A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. The factors of 39 are 1, 3, 13, and 39. The common factors are 1 and 3. Therefore, the greatest common factor is 3.
The common factors are 1, 3 and 9.
