The HCF of 156, 455 and 1183 is:
Given:
We need to find the Highest Common Factor (HCF) of 156, 455, and 1183 using the factor method.
Factorization:
First, we find the prime factorization of each number:
156 = 2 × 2 × 3 × 13
455 = 5 × 7 × 13
1183 = 13 × 91 = 13 × 7 × 13
Solution:
The common factor among all numbers is 13.
HCF(156, 455, 1183) = 13
