To get the Greatest Common Factor (GCF) of 18 and 90 we need to factor each value first and then we choose all the copies of factors and multiply them: 18: 233
90: 2335
GCF: 233
The Greatest Common Factor (GCF) is: 2 x 3 x 3 = 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
The GCF is 18.
The GCF is 18.
The GCF is 18.
The GCF is: 18
The GCF is 18.
