Question

Find the HCF of 12, 13 by long division.​

Answer 1

Step-by-step explanation:

There are 3 commonly used methods to find the GCF of 12 and 13 - long division, prime factorization, and Euclidean algorithm.

...

GCF of 12 and 13 by Prime Factorization

GCF of 9 and 12 = 3.

GCF of 48 and 16 = 16.

GCF of 63 and 84 = 21.

GCF of 9 and 15 = 3.

GCF of 36 and 81 = 9.

GCF of 24 and 96 = 24.

GCF of 6 and 18 = 6.

Answer 2

The factors of 12 are 1, 2, 3, 4, 6 and 12. The factors of 13 are 1 and 13. So, the Greatest Common Factor for these numbers is 1 because it divides all them without a remainder.
