Best Answer

The greatest common factor of 30, 24, and 18 is 6.

You can use the factor tree used to find the prime factorization.

18<6*3

6<3*2

so 18= 3*2*3

24<6*4

6<3*2

4<2*2

so 24=3*2*2*2

30<6*5

6<3*2

so 30=3*2*5

find you common factors... CF: 3 & 2

so you would multiply 3*2=6 this gives you your answer

there are more methods that you can use to help find you greatest common factor (GCF)
