HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 868, 471 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 868, 471 is 1 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 868, 471 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 868, 471 is 1.

HCF(868, 471) = 1

Highest common factor (HCF) of 868, 471 is 1.

Highest Common Factor of 868,471 using Euclid's algorithm

Highest Common Factor of 868,471 is 1

Step 1: Since 868 > 471, we apply the division lemma to 868 and 471, to get

868 = 471 x 1 + 397

Step 2: Since the reminder 471 ≠ 0, we apply division lemma to 397 and 471, to get

471 = 397 x 1 + 74

Step 3: We consider the new divisor 397 and the new remainder 74, and apply the division lemma to get

397 = 74 x 5 + 27

We consider the new divisor 74 and the new remainder 27,and apply the division lemma to get

74 = 27 x 2 + 20

We consider the new divisor 27 and the new remainder 20,and apply the division lemma to get

27 = 20 x 1 + 7

We consider the new divisor 20 and the new remainder 7,and apply the division lemma to get

20 = 7 x 2 + 6

We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get

7 = 6 x 1 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 868 and 471 is 1

Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(20,7) = HCF(27,20) = HCF(74,27) = HCF(397,74) = HCF(471,397) = HCF(868,471) .
