The factors of 18 are 1, 2, 3, 6, 9 and 18. For any of them to be common, they need to be compared to another set of factors.
Since 18 is a factor of 54, put the factors of 18 (except for 18) in the left circle, the factors of 54 (except for 18) in the right circle, and put 18 in the center where they intersect.
It can be. 18 is a common factor of 36 and 54.
Since 18 is a factor of 90 and it is the largest factor of itself, the greatest common factor of 18 and 90 is 18.Since 18 is a factor of 90, it is automatically the GCF.
The greatest common factor is 18.
The greatest common factor is 18.
The greatest common factor of 18 and 55 is 1.
The greatest common factor of 39 and 18 is definitely 3.
It is 1 but the highest common factor is 18
The GCF ( greatest common factor) is 2 I know for a fact this is the correct answer Greatest common factor means the factor that goes (for example) 18 and 20, but the biggest.
Since 18 is a factor of 72, all of its factors are common.
The Greatest Common Factor of 40 and 18 is 2.
The greatest common factor of 18 , 7 = 1
