HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 813, 991, 349 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 813, 991, 349 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 813, 991, 349 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 813, 991, 349 is 1.

HCF(813, 991, 349) = 1

HCF of 813, 991, 349 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 813, 991, 349 is 1.

Highest Common Factor of 813,991,349 using Euclid's algorithm

Highest Common Factor of 813,991,349 is 1

Step 1: Since 991 > 813, we apply the division lemma to 991 and 813, to get

991 = 813 x 1 + 178

Step 2: Since the reminder 813 ≠ 0, we apply division lemma to 178 and 813, to get

813 = 178 x 4 + 101

Step 3: We consider the new divisor 178 and the new remainder 101, and apply the division lemma to get

178 = 101 x 1 + 77

We consider the new divisor 101 and the new remainder 77,and apply the division lemma to get

101 = 77 x 1 + 24

We consider the new divisor 77 and the new remainder 24,and apply the division lemma to get

77 = 24 x 3 + 5

We consider the new divisor 24 and the new remainder 5,and apply the division lemma to get

24 = 5 x 4 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 813 and 991 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(24,5) = HCF(77,24) = HCF(101,77) = HCF(178,101) = HCF(813,178) = HCF(991,813) .

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

Step 1: Since 349 > 1, we apply the division lemma to 349 and 1, to get

349 = 1 x 349 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 349 is 1

Notice that 1 = HCF(349,1) .
