The GCF is 13.
The GCF is 13.
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.
The GCF is 13.
The answer is: 1
Factors of 91: 1, 7, 13, 91Factors of 117: 1, 3, 9, 13, 39, 117GCF (91, 117) = 13
None of these numbers are prime: 91 is divisible by 7 117 is divisible by 3 84 and 156 are both divisible by 2
The GCF of 91 and 156 is 13.The prime factorization of 91 is 7*13.The prime factorization of 156 is 2*2*3*13So the GCF is 13.
The GCF is 13.
45 = 5 x 9, 117 = 13 x 9. 5 and 13 are co-prime so GCF is 9.
The GCF of 13, 65 and 117 is 13. The GCF of 1365 and 117 is 39.
Well, isn't that just a happy little math question! To simplify 91 over 117, we can divide both numbers by their greatest common factor, which is 13. So, 91 divided by 13 is 7, and 117 divided by 13 is 9. Therefore, the simplest form of 91 over 117 is 7 over 9. Just like that, we've created a beautiful fraction!
