HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 711, 491 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 711, 491 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 711, 491 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 711, 491 is 1.

HCF(711, 491) = 1

HCF of 711, 491 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 711, 491 is 1.

Highest Common Factor of 711,491 using Euclid's algorithm

Highest Common Factor of 711,491 is 1

Step 1: Since 711 > 491, we apply the division lemma to 711 and 491, to get

711 = 491 x 1 + 220

Step 2: Since the reminder 491 ≠ 0, we apply division lemma to 220 and 491, to get

491 = 220 x 2 + 51

Step 3: We consider the new divisor 220 and the new remainder 51, and apply the division lemma to get

220 = 51 x 4 + 16

We consider the new divisor 51 and the new remainder 16,and apply the division lemma to get

51 = 16 x 3 + 3

We consider the new divisor 16 and the new remainder 3,and apply the division lemma to get

16 = 3 x 5 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 711 and 491 is 1

Notice that 1 = HCF(3,1) = HCF(16,3) = HCF(51,16) = HCF(220,51) = HCF(491,220) = HCF(711,491) .
