HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 868, 551, 375, 477 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 868, 551, 375, 477 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, 551, 375, 477 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, 551, 375, 477 is 1.

HCF(868, 551, 375, 477) = 1

Highest common factor (HCF) of 868, 551, 375, 477 is 1.

Highest Common Factor of 868,551,375,477 using Euclid's algorithm

Highest Common Factor of 868,551,375,477 is 1

Step 1: Since 868 > 551, we apply the division lemma to 868 and 551, to get

868 = 551 x 1 + 317

Step 2: Since the reminder 551 ≠ 0, we apply division lemma to 317 and 551, to get

551 = 317 x 1 + 234

Step 3: We consider the new divisor 317 and the new remainder 234, and apply the division lemma to get

317 = 234 x 1 + 83

We consider the new divisor 234 and the new remainder 83,and apply the division lemma to get

234 = 83 x 2 + 68

We consider the new divisor 83 and the new remainder 68,and apply the division lemma to get

83 = 68 x 1 + 15

We consider the new divisor 68 and the new remainder 15,and apply the division lemma to get

68 = 15 x 4 + 8

We consider the new divisor 15 and the new remainder 8,and apply the division lemma to get

15 = 8 x 1 + 7

We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get

8 = 7 x 1 + 1

We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get

7 = 1 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 868 and 551 is 1

Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(15,8) = HCF(68,15) = HCF(83,68) = HCF(234,83) = HCF(317,234) = HCF(551,317) = HCF(868,551) .

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

Step 1: Since 375 > 1, we apply the division lemma to 375 and 1, to get

375 = 1 x 375 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 375 is 1

Notice that 1 = HCF(375,1) .

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

Step 1: Since 477 > 1, we apply the division lemma to 477 and 1, to get

477 = 1 x 477 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 477 is 1

Notice that 1 = HCF(477,1) .
