HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 834, 355, 812 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 834, 355, 812 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 834, 355, 812 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 834, 355, 812 is 1.

HCF(834, 355, 812) = 1

Highest common factor (HCF) of 834, 355, 812 is 1.

Highest Common Factor of 834,355,812 using Euclid's algorithm

Highest Common Factor of 834,355,812 is 1

Step 1: Since 834 > 355, we apply the division lemma to 834 and 355, to get

834 = 355 x 2 + 124

Step 2: Since the reminder 355 ≠ 0, we apply division lemma to 124 and 355, to get

355 = 124 x 2 + 107

Step 3: We consider the new divisor 124 and the new remainder 107, and apply the division lemma to get

124 = 107 x 1 + 17

We consider the new divisor 107 and the new remainder 17,and apply the division lemma to get

107 = 17 x 6 + 5

We consider the new divisor 17 and the new remainder 5,and apply the division lemma to get

17 = 5 x 3 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 1

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 834 and 355 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(17,5) = HCF(107,17) = HCF(124,107) = HCF(355,124) = HCF(834,355) .

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

Step 1: Since 812 > 1, we apply the division lemma to 812 and 1, to get

812 = 1 x 812 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 812 is 1

Notice that 1 = HCF(812,1) .
