HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 859, 629, 422 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 859, 629, 422 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 859, 629, 422 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 859, 629, 422 is 1.

HCF(859, 629, 422) = 1

Highest common factor (HCF) of 859, 629, 422 is 1.

Highest Common Factor of 859,629,422 using Euclid's algorithm

Highest Common Factor of 859,629,422 is 1

Step 1: Since 859 > 629, we apply the division lemma to 859 and 629, to get

859 = 629 x 1 + 230

Step 2: Since the reminder 629 ≠ 0, we apply division lemma to 230 and 629, to get

629 = 230 x 2 + 169

Step 3: We consider the new divisor 230 and the new remainder 169, and apply the division lemma to get

230 = 169 x 1 + 61

We consider the new divisor 169 and the new remainder 61,and apply the division lemma to get

169 = 61 x 2 + 47

We consider the new divisor 61 and the new remainder 47,and apply the division lemma to get

61 = 47 x 1 + 14

We consider the new divisor 47 and the new remainder 14,and apply the division lemma to get

47 = 14 x 3 + 5

We consider the new divisor 14 and the new remainder 5,and apply the division lemma to get

14 = 5 x 2 + 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 859 and 629 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(47,14) = HCF(61,47) = HCF(169,61) = HCF(230,169) = HCF(629,230) = HCF(859,629) .

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

Step 1: Since 422 > 1, we apply the division lemma to 422 and 1, to get

422 = 1 x 422 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 422 is 1

Notice that 1 = HCF(422,1) .
