HCF of 336 and 54 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 = 336 and Y = 54
 HCF(336, 54) = HCF(54, 336 mod 54) = HCF(54, 12)
 HCF(54, 12) = HCF(12, 54 mod 12) = HCF(12, 6)
 HCF(12, 6) = HCF(6, 12 mod 6) = HCF(6, 0)
 HCF(6, 0) = 6 (∵ HCF(X, 0) = X, where X ≠ 0)
Therefore, the value of HCF of 336 and 54 is 6.
