18 = 2x3x3 so the factors of 18 are 1, 2, 3, 6, 9, 18
90 = 2x3x3x5 so the factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
The gcf of 18 and 90 is 2x3x3 = 18
The GCF is 18.
The GCF of 54, 90, and 126 is 9
The GCF is 18.
The GCF is 18.
The GCF is 18.
Since 18 is a factor of 90, it is automatically the GCF.
GCF of 36 and 90 is 18
It is 18 which the highest number that will divide into both of them with no remainder
The GCF is 18.
The GCF is 18.
The GCF is 18.
The GCF is: 18
