HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 829, 491, 549 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 829, 491, 549 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 829, 491, 549 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 829, 491, 549 is 1.

HCF(829, 491, 549) = 1

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

HCF of:

Highest common factor (HCF) of 829, 491, 549 is 1.

Highest Common Factor of 829,491,549 using Euclid's algorithm

Highest Common Factor of 829,491,549 is 1

Step 1: Since 829 > 491, we apply the division lemma to 829 and 491, to get

829 = 491 x 1 + 338

Step 2: Since the reminder 491 ≠ 0, we apply division lemma to 338 and 491, to get

491 = 338 x 1 + 153

Step 3: We consider the new divisor 338 and the new remainder 153, and apply the division lemma to get

338 = 153 x 2 + 32

We consider the new divisor 153 and the new remainder 32,and apply the division lemma to get

153 = 32 x 4 + 25

We consider the new divisor 32 and the new remainder 25,and apply the division lemma to get

32 = 25 x 1 + 7

We consider the new divisor 25 and the new remainder 7,and apply the division lemma to get

25 = 7 x 3 + 4

We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get

7 = 4 x 1 + 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 829 and 491 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(25,7) = HCF(32,25) = HCF(153,32) = HCF(338,153) = HCF(491,338) = HCF(829,491) .

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

Step 1: Since 549 > 1, we apply the division lemma to 549 and 1, to get

549 = 1 x 549 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 549 is 1

Notice that 1 = HCF(549,1) .
