To find the Highest Common Factor (HCF) of 867 and 255 using Euclid’s division algorithm, we follow a systematic approach involving division and remainders.
Step 1: Initial Division
First, divide the larger number by the smaller number:
- 867 ÷ 255 = 3 (quotient)
- Remainder = 867 - (255 × 3) = 102
Step 2: Repeat the Process
Now, take the previous divisor (255) and divide it by the remainder (102):
- 255 ÷ 102 = 2 (quotient)
- Remainder = 255 - (102 × 2) = 51
Step 3: Continue Dividing
Next, divide the last divisor (102) by the new remainder (51):
- 102 ÷ 51 = 2 (quotient)
- Remainder = 102 - (51 × 2) = 0
Final Result
Since the remainder is now 0, the last non-zero remainder is the HCF. Therefore, the HCF of 867 and 255 is:
51
