HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 171, 418 i.e. 19 the largest integer that leaves a remainder zero for all numbers.

HCF of 171, 418 is 19 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 171, 418 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 171, 418 is 19.

HCF(171, 418) = 19

Highest common factor (HCF) of 171, 418 is 19.

Highest Common Factor of 171,418 using Euclid's algorithm

Highest Common Factor of 171,418 is 19

Step 1: Since 418 > 171, we apply the division lemma to 418 and 171, to get

418 = 171 x 2 + 76

Step 2: Since the reminder 171 ≠ 0, we apply division lemma to 76 and 171, to get

171 = 76 x 2 + 19

Step 3: We consider the new divisor 76 and the new remainder 19, and apply the division lemma to get

76 = 19 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 19, the HCF of 171 and 418 is 19

Notice that 19 = HCF(76,19) = HCF(171,76) = HCF(418,171) .
