Best Answer

The Highest Common Factor (HCF) of 280 and 180 is the largest positive integer that divides both numbers without leaving a remainder. To find the HCF, you can use the Euclidean algorithm or prime factorization method. In this case, the prime factorization of 280 is 2^3 * 5 * 7 and the prime factorization of 180 is 2^2 * 3^2 * 5. The common factors between the two numbers are 2^2 and 5, so the HCF of 280 and 180 is 20.
