The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 45 and 285 is 15
285
The Highest Common Factor (HCF) of 165, 195, and 285 is the largest number that divides all three numbers evenly. To find the HCF, we first factorize each number: 165 = 3 x 5 x 11, 195 = 3 x 5 x 13, and 285 = 3 x 5 x 19. Then, we identify the common factors among the three numbers, which are 3 and 5. Therefore, the HCF of 165, 195, and 285 is 15 (3 x 5).
The numbers are: 93+95+97 = 285
