HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 512, 786, 422 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 512, 786, 422 is 2 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 512, 786, 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 512, 786, 422 is 2.

HCF(512, 786, 422) = 2

Highest common factor (HCF) of 512, 786, 422 is 2.

Highest Common Factor of 512,786,422 using Euclid's algorithm

Highest Common Factor of 512,786,422 is 2

Step 1: Since 786 > 512, we apply the division lemma to 786 and 512, to get

786 = 512 x 1 + 274

Step 2: Since the reminder 512 ≠ 0, we apply division lemma to 274 and 512, to get

512 = 274 x 1 + 238

Step 3: We consider the new divisor 274 and the new remainder 238, and apply the division lemma to get

274 = 238 x 1 + 36

We consider the new divisor 238 and the new remainder 36,and apply the division lemma to get

238 = 36 x 6 + 22

We consider the new divisor 36 and the new remainder 22,and apply the division lemma to get

36 = 22 x 1 + 14

We consider the new divisor 22 and the new remainder 14,and apply the division lemma to get

22 = 14 x 1 + 8

We consider the new divisor 14 and the new remainder 8,and apply the division lemma to get

14 = 8 x 1 + 6

We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get

8 = 6 x 1 + 2

We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get

6 = 2 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 512 and 786 is 2

Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(14,8) = HCF(22,14) = HCF(36,22) = HCF(238,36) = HCF(274,238) = HCF(512,274) = HCF(786,512) .


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

Step 1: Since 422 > 2, we apply the division lemma to 422 and 2, to get

422 = 2 x 211 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 422 is 2

Notice that 2 = HCF(422,2) .
