HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 779, 947, 814 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 779, 947, 814 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 779, 947, 814 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 779, 947, 814 is 1.

HCF(779, 947, 814) = 1

HCF of 779, 947, 814 using Euclid's algorithm

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

Highest common factor (HCF) of 779, 947, 814 is 1.

Highest Common Factor of 779,947,814 using Euclid's algorithm

Highest Common Factor of 779,947,814 is 1

Step 1: Since 947 > 779, we apply the division lemma to 947 and 779, to get

947 = 779 x 1 + 168

Step 2: Since the reminder 779 ≠ 0, we apply division lemma to 168 and 779, to get

779 = 168 x 4 + 107

Step 3: We consider the new divisor 168 and the new remainder 107, and apply the division lemma to get

168 = 107 x 1 + 61

We consider the new divisor 107 and the new remainder 61,and apply the division lemma to get

107 = 61 x 1 + 46

We consider the new divisor 61 and the new remainder 46,and apply the division lemma to get

61 = 46 x 1 + 15

We consider the new divisor 46 and the new remainder 15,and apply the division lemma to get

46 = 15 x 3 + 1

We consider the new divisor 15 and the new remainder 1,and apply the division lemma to get

15 = 1 x 15 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 779 and 947 is 1

Notice that 1 = HCF(15,1) = HCF(46,15) = HCF(61,46) = HCF(107,61) = HCF(168,107) = HCF(779,168) = HCF(947,779) .

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

Step 1: Since 814 > 1, we apply the division lemma to 814 and 1, to get

814 = 1 x 814 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 814 is 1

Notice that 1 = HCF(814,1) .
