Prime factorization of 12 = 2x2x3
Prime factorization of 34 = 2x17
From the P.F. of both numbers 2 is the common factor. Therefore, GCF =2.
Same as the gcf of 12 and 9 (where 9 is the remainder of the division of 33 by 12).
The GCF of 11 and 66 is 11. Since 11 is a factor of 66, it is automatically the GCF.
The GCF is 1.
The GCF of 33 and 121 is 11.The GCF is 11.It is: 11
The GCF of 242 and 2123 is 11.
The factors of 33 are:1, 3, 11, 33The factors of 99 are:1, 3, 9, 11, 33, 99The common factors are:1, 3, 11, 33The Greatest Common Factor (GCF) is:33
