The GCF is 26. The LCM is 312.
39, 78, 117, 195, 312 and 936 are divisible by three.
To find the Greatest Common Factor (GCF) of 52, 78, 91, and 117, we first need to find the prime factorization of each number. The prime factorization of 52 is 2^2 * 13, 78 is 2 * 3 * 13, 91 is 7 * 13, and 117 is 3^2 * 13. The common prime factors among these numbers are 13. Therefore, the GCF of 52, 78, 91, and 117 is 13.
13 is a factor of both 78 (6 times) and 104 (8 times).Since 13 is also obviously a factor of itself, it must be the greatest factorthat's common to all three numbers.(If there were a greater one, then 13 would have a factor greater than itself.)
The GCF is 26.
