The GCF is 1.
No, 9 is not a factor of either number.
Numbers that have no common factor like 8 and 9 as 8=23 and 9=32 The two of them are not prime but they have no common factor
Since 16 is a factor of 32, it is automatically the GCF.
The greatest prime factor they have in common is 2.
9. 63 = 32 x 7 90 = 2 x 32 x 5 gcf = 32 = 9
The common factor of 32 and 45 is 1. The factors of 32 are 1, 2, 4, 8, 16, and 32 The factors of 45 are 1, 3, 5, 9, 15, and 45 The only common factor of 32 and 45 is 1.
The GCF is 32.
The greatest common factor of 18 and 32 is 2.2 x 9 = 182 x 16 = 32
The greatest common factor of 90 and 216 is 18 90 = 2 * 32 * 5 216 = 23 * 33 greatest common factor = 2 * 32 = 2 * 9 = 18 90 / 18 = 5 216 / 18 = 12 because the greatest common factor of these is 1.
The Greatest Common Factor of the two numbers is 9. 288/9 = 32, 405/9 = 45.
The greatest common factor of 9 and 33 is 3It is: 3
