HCF of 867 and 225 by Listing Common Factors
- Factors of 867: 1, 3, 17, 51, 289, 867
- Factors of 225: 1, 3, 5, 9, 15, 25, 45, 75, 225
There are 2 common factors of 867 and 225, that are 1 and 3. Therefore, the highest common factor of 867 and 225 is 3.
HCF of 867 and 225 by Euclidean Algorithm
As per the Euclidean Algorithm, HCF(X, Y) = HCF(Y, X mod Y)
where X > Y and mod is the modulo operator.
Here X = 867 and Y = 225
- HCF(867, 225) = HCF(225, 867 mod 225) = HCF(225, 192)
- HCF(225, 192) = HCF(192, 225 mod 192) = HCF(192, 33)
- HCF(192, 33) = HCF(33, 192 mod 33) = HCF(33, 27)
- HCF(33, 27) = HCF(27, 33 mod 27) = HCF(27, 6)
- HCF(27, 6) = HCF(6, 27 mod 6) = HCF(6, 3)
- HCF(6, 3) = HCF(3, 6 mod 3) = HCF(3, 0)
- HCF(3, 0) = 3 (∵ HCF(X, 0) = |X|, where X ≠ 0)
Therefore, the value of HCF of 867 and 225 is 3.
HCF of 867 and 225 by Long Division
HCF of 867 and 225 is the divisor that we get when the remainder becomes 0 after doing long division repeatedly.
