To answer this question you first need to isolate the prime factors in each number. In this case the numbers are 36 and 18 so the prime factors are:
18 = 2x3x3
36 = 2x2x3x3
The next step is to identify any unique factors. In this case, the only prime factor 36 has which 18 doesn't is a second 2. Thus any combination of the prime factors of 36 which includes both 2s will not be a factor of 18. These numbers are 4, 12 and 36.
You need at least two numbers to find a GCF.
The Greatest Common Factor depends upon the numbers for which there are common factors and it is the greatest one of them; it can be greater than 18, for example the greatest common factor of 40 and 100 is 20. The greatest common factor must be one of the factors of each of the numbers. As the factors of each number cannot be greater than that number, the greatest common factor of a set of numbers cannot be greater than the least number. If this number is not greater than 18 then the greatest common factor of the numbers cannot be greater than 18. Even if the least number is greater than 18 it is possible that the greatest common factor of a set of numbers is still not greater than 18, for example the greatest common factor of 20, 30 and 50 is 10.
the LCM [lowest common multiple] of 18 and 24 is 72. The factors of 18 are 18, 36, 54, and 72. the factors of 24 are 24, 48, and 72. therefor, the LCM is 72.
You need at least two numbers to find a GCF. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, 36. For them to be common, they need to be compared to another set of factors.
The common factors of 36 are 1, 2, 3, 6, 12 and 18.
18 and 36
The common factors of 18 and 36 are 18,9,6,3,2,1.
The common prime factors of 18 and 36 are 2 and 3. Both numbers can be divided evenly by 2 and 3.

Since 18 is a factor of 36, all the factors of 18 will be common to 36. 1,2,3,6,9,18
The greatest common factor of 36 and 90 is 18.The common factors of 36 and 90 are 1, 2, 3, 6, 9, and 18.Definition: A factor is a divisor - a number that will evenly divide into another number. The common factors of two or more numbers are all the factors that the numbers have in common. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Methods: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 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90.The common factors are 1, 2, 3, 6, 9, and 18. Therefore, the greatest common factor is 18.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 36 are 2, 2, 3, and 3.The prime factors of 90 are 2, 3, 3, and 5.The prime factors in common are 2, 3, and 3, so the greatest common factor is 2 x 3 x 3 = 18.
1, 2, 3, 6, 9, 18
the LCM [lowest common multiple] of 18 and 24 is 72. The factors of 18 are 18, 36, 54, and 72. the factors of 24 are 24, 48, and 72. therefor, the LCM is 72.
63 ... 3, 7, 9, 21, 63 36 ... 2, 3, 4, 6, 9, 12, 18, 36 common factors ... 3, 9
You need at least two numbers to find a GCF. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, 36. For them to be common, they need to be compared to another set of factors.
There cannot be a common factor of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, 36
