HCF of 6 and 24 by Long Division
HCF of 6 and 24 is the divisor that we get when the remainder becomes 0 after doing long division repeatedly.
- Step 1: Divide 24 (larger number) by 6 (smaller number).
- Step 2: Since the remainder = 0, the divisor (6) is the HCF of 6 and 24.
The corresponding divisor (6) is the HCF of 6 and 24.
HCF of 6 and 24 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 = 24 and Y = 6
- HCF(24, 6) = HCF(6, 24 mod 6) = HCF(6, 0)
- HCF(6, 0) = 6 (∵ HCF(X, 0) = |X|, where X ≠ 0)
Therefore, the value of HCF of 6 and 24 is 6.
