The highest common factor (HCF) of 245 and 210 is 35. To find the HCF, you need to identify the common factors of both numbers and then determine the highest one they share. In this case, the factors of 245 are 1, 5, 7, 35, 49, 245, and the factors of 210 are 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210. The highest common factor of 245 and 210 is 35 because it is the largest number that divides both 245 and 210 without leaving a remainder.
