HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 472, 718, 811 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 472, 718, 811 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 472, 718, 811 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 472, 718, 811 is 1.

HCF(472, 718, 811) = 1

Highest common factor (HCF) of 472, 718, 811 is 1.

Highest Common Factor of 472,718,811 using Euclid's algorithm

Highest Common Factor of 472,718,811 is 1

Step 1: Since 718 > 472, we apply the division lemma to 718 and 472, to get

718 = 472 x 1 + 246

Step 2: Since the reminder 472 ≠ 0, we apply division lemma to 246 and 472, to get

472 = 246 x 1 + 226

Step 3: We consider the new divisor 246 and the new remainder 226, and apply the division lemma to get

246 = 226 x 1 + 20

We consider the new divisor 226 and the new remainder 20,and apply the division lemma to get

226 = 20 x 11 + 6

We consider the new divisor 20 and the new remainder 6,and apply the division lemma to get

20 = 6 x 3 + 2

We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get

6 = 2 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 472 and 718 is 2

Notice that 2 = HCF(6,2) = HCF(20,6) = HCF(226,20) = HCF(246,226) = HCF(472,246) = HCF(718,472) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 811 > 2, we apply the division lemma to 811 and 2, to get

811 = 2 x 405 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 811 is 1

Notice that 1 = HCF(2,1) = HCF(811,2) .
