To find the greatest common factor (GCF) of 78, 156, and 169, we first need to find the prime factorization of each number. The prime factorization of 78 is 2 x 3 x 13. The prime factorization of 156 is 2 x 2 x 3 x 13. The prime factorization of 169 is 13 x 13. The GCF is the product of the common prime factors raised to the lowest power, which in this case is 13. Therefore, the GCF of 78, 156, and 169 is 13.
The GCF of 169 and 343 is 1.
The GCF of 52, 143, and 169 is 13.
The GCF is 4.
Since 36 is a factor of 144, it is automatically the GCF.
The GCF is 13.
The GCF is 13.
The GCF is 13.
