MCQ
The $\text{HCF}$ of $867$ and $255$ is :
- A$35$
- ✓$51$
- C$55$
- D$25$
✓
Answer
Correct option: B.
$51$
$867 = 255 \times 3 + 102$
$255 = 102 \times 2 + 51$
$102 = 51 \times 2 + 0$
Hence, we got remainder as $0,$
therefore $\text{HCF}$ of $(867, 255)$ is $51$
$255 = 102 \times 2 + 51$
$102 = 51 \times 2 + 0$
Hence, we got remainder as $0,$
therefore $\text{HCF}$ of $(867, 255)$ is $51$
