The common factors are: 1, 2, 4
The common factors of 12, 20 and 36 are: 1, 2, and 4
The common factors of 20, 36, and 48 are 1, 2 and 4
The common factors of 20, 28, and 36 are 1, 2 and 4
The common factors of 21 and 36 are 1 and 3
The common factors of 8, 20, and 36 are the numbers that can divide each of these numbers without leaving a remainder. The factors of 8 are 1, 2, 4, and 8. 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 8, 20, and 36 are 1, 2, and 4.
The Greatest Common Factor (GCF) of 20 and 36 is: 4
The common factors of 18 and 36 are 18,9,6,3,2,1.
Since 12 is a factor of 36, all of the factors of 12 are common to 36.
Since 9 is a factor of 36, all of its factors are common.
Since 18 is a factor of 36, all the factors of 18 will be common to 36. 1,2,3,6,9,18
Common factors of 36 and 40 are: 1, 2, and 4.
-- 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.
