HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 511, 779, 363 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 511, 779, 363 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 511, 779, 363 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 511, 779, 363 is 1.

HCF(511, 779, 363) = 1

HCF of 511, 779, 363 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 511, 779, 363 is 1.

Highest Common Factor of 511,779,363 using Euclid's algorithm

Highest Common Factor of 511,779,363 is 1

Step 1: Since 779 > 511, we apply the division lemma to 779 and 511, to get

779 = 511 x 1 + 268

Step 2: Since the reminder 511 ≠ 0, we apply division lemma to 268 and 511, to get

511 = 268 x 1 + 243

Step 3: We consider the new divisor 268 and the new remainder 243, and apply the division lemma to get

268 = 243 x 1 + 25

We consider the new divisor 243 and the new remainder 25,and apply the division lemma to get

243 = 25 x 9 + 18

We consider the new divisor 25 and the new remainder 18,and apply the division lemma to get

25 = 18 x 1 + 7

We consider the new divisor 18 and the new remainder 7,and apply the division lemma to get

18 = 7 x 2 + 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 511 and 779 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(18,7) = HCF(25,18) = HCF(243,25) = HCF(268,243) = HCF(511,268) = HCF(779,511) .

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

Step 1: Since 363 > 1, we apply the division lemma to 363 and 1, to get

363 = 1 x 363 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 363 is 1

Notice that 1 = HCF(363,1) .
