Best Answer

The Highest Common Factor (HCF) of two numbers is the largest positive integer that divides both numbers without leaving a remainder. To find the HCF of 210 and 504, you can use the Euclidean algorithm or prime factorization method. In this case, the prime factorization of 210 is 2 x 3 x 5 x 7, and the prime factorization of 504 is 2^3 x 3^2 x 7. To find the HCF, you take the common prime factors with the lowest exponents, which are 2 x 3 x 7 = 42. Therefore, the HCF of 210 and 504 is 42.
