The highest common factor (HCF) of 228 and 285 is the largest positive integer that divides both numbers without leaving a remainder. To find the HCF, you can use the Euclidean algorithm. First, divide the larger number (285) by the smaller number (228) to get a quotient of 1 with a remainder of 57. Then, divide the previous divisor (228) by the remainder (57) to get a quotient of 4 with a remainder of 0. Therefore, the HCF of 228 and 285 is 57.
(60 × 4) + 45 = 285 minutes Method: There are 60 minutes in 1 hour: 60 minutes x 4 hours equals 240 minutes. There are 45 minutes in 3 quarters of 1 hour. Therefore, add 240 and 45 which equals 285 minutes.

Well, let's see. So we can try 285/9 It is 31 with 6 as it's remainder. You know that the dividend is the largest number, and the divisor would be less than the dividend. Since the divisor can't be any smaller than the remainder so would the dividend. Because it will be the only LARGEST number in the division equation.
√285 = 16.881943
