HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 857, 1129, 3022 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 857, 1129, 3022 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 857, 1129, 3022 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 857, 1129, 3022 is 1.

HCF(857, 1129, 3022) = 1

Highest common factor (HCF) of 857, 1129, 3022 is 1.

Highest Common Factor of 857,1129,3022 using Euclid's algorithm

Highest Common Factor of 857,1129,3022 is 1

Step 1: Since 1129 > 857, we apply the division lemma to 1129 and 857, to get

1129 = 857 x 1 + 272

Step 2: Since the reminder 857 ≠ 0, we apply division lemma to 272 and 857, to get

857 = 272 x 3 + 41

Step 3: We consider the new divisor 272 and the new remainder 41, and apply the division lemma to get

272 = 41 x 6 + 26

We consider the new divisor 41 and the new remainder 26,and apply the division lemma to get

41 = 26 x 1 + 15

We consider the new divisor 26 and the new remainder 15,and apply the division lemma to get

26 = 15 x 1 + 11

We consider the new divisor 15 and the new remainder 11,and apply the division lemma to get

15 = 11 x 1 + 4

We consider the new divisor 11 and the new remainder 4,and apply the division lemma to get

11 = 4 x 2 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 857 and 1129 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(15,11) = HCF(26,15) = HCF(41,26) = HCF(272,41) = HCF(857,272) = HCF(1129,857) .

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

Step 1: Since 3022 > 1, we apply the division lemma to 3022 and 1, to get

3022 = 1 x 3022 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 3022 is 1

Notice that 1 = HCF(3022,1) .
