1, 2 and 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 are: 1, 2, 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.
The only common factors are: 1, 3
One way to determine the greatest common factor is to find all the factors of the numbers and compare them.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 are 1, 2, and 4. Therefore, the greatest common factor is 4.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 20 are 2, 2, and 5.The prime factors of 36 are 2, 2, 3, and 3.The prime factors in common are 2 and 2, so the greatest common factor is 2 x 2 = 4.The factors of 20 are: 1, 2, 4, 5, 10, 20The factors of 36 are:1, 2, 3, 4, 6, 9, 12, 18, 36The common factors are:1, 2, 4The Greatest Common Factor:GCF = 4
Common factors of 36, 42, and 48 are: 1, 2, 3, and 6.
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.
