HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 431, 4869, 2773 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 431, 4869, 2773 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 431, 4869, 2773 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 431, 4869, 2773 is 1.

HCF(431, 4869, 2773) = 1

Highest common factor (HCF) of 431, 4869, 2773 is 1.

Highest Common Factor of 431,4869,2773 using Euclid's algorithm

Highest Common Factor of 431,4869,2773 is 1

Step 1: Since 4869 > 431, we apply the division lemma to 4869 and 431, to get

4869 = 431 x 11 + 128

Step 2: Since the reminder 431 ≠ 0, we apply division lemma to 128 and 431, to get

431 = 128 x 3 + 47

Step 3: We consider the new divisor 128 and the new remainder 47, and apply the division lemma to get

128 = 47 x 2 + 34

We consider the new divisor 47 and the new remainder 34,and apply the division lemma to get

47 = 34 x 1 + 13

We consider the new divisor 34 and the new remainder 13,and apply the division lemma to get

34 = 13 x 2 + 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 431 and 4869 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(34,13) = HCF(47,34) = HCF(128,47) = HCF(431,128) = HCF(4869,431) .

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

Step 1: Since 2773 > 1, we apply the division lemma to 2773 and 1, to get

2773 = 1 x 2773 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 2773 is 1

Notice that 1 = HCF(2773,1) .
