HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 477, 878, 194 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 477, 878, 194 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 477, 878, 194 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 477, 878, 194 is 1.

HCF(477, 878, 194) = 1

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

HCF of:

Highest common factor (HCF) of 477, 878, 194 is 1.

Highest Common Factor of 477,878,194 using Euclid's algorithm

Highest Common Factor of 477,878,194 is 1

Step 1: Since 878 > 477, we apply the division lemma to 878 and 477, to get

878 = 477 x 1 + 401

Step 2: Since the reminder 477 ≠ 0, we apply division lemma to 401 and 477, to get

477 = 401 x 1 + 76

Step 3: We consider the new divisor 401 and the new remainder 76, and apply the division lemma to get

401 = 76 x 5 + 21

We consider the new divisor 76 and the new remainder 21,and apply the division lemma to get

76 = 21 x 3 + 13

We consider the new divisor 21 and the new remainder 13,and apply the division lemma to get

21 = 13 x 1 + 8

We consider the new divisor 13 and the new remainder 8,and apply the division lemma to get

13 = 8 x 1 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 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 477 and 878 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(21,13) = HCF(76,21) = HCF(401,76) = HCF(477,401) = HCF(878,477) .

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

Step 1: Since 194 > 1, we apply the division lemma to 194 and 1, to get

194 = 1 x 194 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 194 is 1

Notice that 1 = HCF(194,1) .
