HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 868, 237, 422 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 868, 237, 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 868, 237, 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 868, 237, 422 is 1.

HCF(868, 237, 422) = 1

HCF of 868, 237, 422 using Euclid's algorithm

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

Highest common factor (HCF) of 868, 237, 422 is 1.

Highest Common Factor of 868,237,422 using Euclid's algorithm

Highest Common Factor of 868,237,422 is 1

Step 1: Since 868 > 237, we apply the division lemma to 868 and 237, to get

868 = 237 x 3 + 157

Step 2: Since the reminder 237 ≠ 0, we apply division lemma to 157 and 237, to get

237 = 157 x 1 + 80

Step 3: We consider the new divisor 157 and the new remainder 80, and apply the division lemma to get

157 = 80 x 1 + 77

We consider the new divisor 80 and the new remainder 77,and apply the division lemma to get

80 = 77 x 1 + 3

We consider the new divisor 77 and the new remainder 3,and apply the division lemma to get

77 = 3 x 25 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 868 and 237 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(77,3) = HCF(80,77) = HCF(157,80) = HCF(237,157) = HCF(868,237) .

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) .
