HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 656, 543, 317 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 656, 543, 317 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 656, 543, 317 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 656, 543, 317 is 1.

HCF(656, 543, 317) = 1

HCF of 656, 543, 317 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 656, 543, 317 is 1.

Highest Common Factor of 656,543,317 using Euclid's algorithm

Highest Common Factor of 656,543,317 is 1

Step 1: Since 656 > 543, we apply the division lemma to 656 and 543, to get

656 = 543 x 1 + 113

Step 2: Since the reminder 543 ≠ 0, we apply division lemma to 113 and 543, to get

543 = 113 x 4 + 91

Step 3: We consider the new divisor 113 and the new remainder 91, and apply the division lemma to get

113 = 91 x 1 + 22

We consider the new divisor 91 and the new remainder 22,and apply the division lemma to get

91 = 22 x 4 + 3

We consider the new divisor 22 and the new remainder 3,and apply the division lemma to get

22 = 3 x 7 + 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 656 and 543 is 1

Notice that 1 = HCF(3,1) = HCF(22,3) = HCF(91,22) = HCF(113,91) = HCF(543,113) = HCF(656,543) .

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

Step 1: Since 317 > 1, we apply the division lemma to 317 and 1, to get

317 = 1 x 317 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 317 is 1

Notice that 1 = HCF(317,1) .
