HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 817, 646, 211, 319 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 817, 646, 211, 319 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 817, 646, 211, 319 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 817, 646, 211, 319 is 1.

HCF(817, 646, 211, 319) = 1

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

HCF of:

Highest common factor (HCF) of 817, 646, 211, 319 is 1.

Highest Common Factor of 817,646,211,319 using Euclid's algorithm

Highest Common Factor of 817,646,211,319 is 1

Step 1: Since 817 > 646, we apply the division lemma to 817 and 646, to get

817 = 646 x 1 + 171

Step 2: Since the reminder 646 ≠ 0, we apply division lemma to 171 and 646, to get

646 = 171 x 3 + 133

Step 3: We consider the new divisor 171 and the new remainder 133, and apply the division lemma to get

171 = 133 x 1 + 38

We consider the new divisor 133 and the new remainder 38,and apply the division lemma to get

133 = 38 x 3 + 19

We consider the new divisor 38 and the new remainder 19,and apply the division lemma to get

38 = 19 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 19, the HCF of 817 and 646 is 19

Notice that 19 = HCF(38,19) = HCF(133,38) = HCF(171,133) = HCF(646,171) = HCF(817,646) .

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

Step 1: Since 211 > 19, we apply the division lemma to 211 and 19, to get

211 = 19 x 11 + 2

Step 2: Since the reminder 19 ≠ 0, we apply division lemma to 2 and 19, to get

19 = 2 x 9 + 1

Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma 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 19 and 211 is 1

Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(211,19) .

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

Step 1: Since 319 > 1, we apply the division lemma to 319 and 1, to get

319 = 1 x 319 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 319 is 1

Notice that 1 = HCF(319,1) .
