You need at least two numbers to find a GCF.
The GCF is 27.
The GCF is 63.
The GCF is 9.
The GCF is 27.
The greatest common factor (GCF) of two numbers is the largest number that divides both numbers without leaving a remainder. To find the GCF of 126 and 189, we can use the prime factorization method. Prime factorizing 126 gives 2 x 3^2 x 7, and prime factorizing 189 gives 3^3 x 7. The common factors between the two numbers are 3 and 7. Therefore, the GCF of 126 and 189 is 21.
126 + 63=189
The GCF of 63, 84 and 126 is 21. The GCF of 6384 and 126 is 42.
The GCF is 27.
The GCF is 14.
