HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 206, 491, 765 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 206, 491, 765 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 206, 491, 765 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 206, 491, 765 is 1.

HCF(206, 491, 765) = 1

HCF of 206, 491, 765 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 206, 491, 765 is 1.

Highest Common Factor of 206,491,765 using Euclid's algorithm

Highest Common Factor of 206,491,765 is 1

Step 1: Since 491 > 206, we apply the division lemma to 491 and 206, to get

491 = 206 x 2 + 79

Step 2: Since the reminder 206 ≠ 0, we apply division lemma to 79 and 206, to get

206 = 79 x 2 + 48

Step 3: We consider the new divisor 79 and the new remainder 48, and apply the division lemma to get

79 = 48 x 1 + 31

We consider the new divisor 48 and the new remainder 31,and apply the division lemma to get

48 = 31 x 1 + 17

We consider the new divisor 31 and the new remainder 17,and apply the division lemma to get

31 = 17 x 1 + 14

We consider the new divisor 17 and the new remainder 14,and apply the division lemma to get

17 = 14 x 1 + 3

We consider the new divisor 14 and the new remainder 3,and apply the division lemma to get

14 = 3 x 4 + 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 206 and 491 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(14,3) = HCF(17,14) = HCF(31,17) = HCF(48,31) = HCF(79,48) = HCF(206,79) = HCF(491,206) .

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

Step 1: Since 765 > 1, we apply the division lemma to 765 and 1, to get

765 = 1 x 765 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 765 is 1

Notice that 1 = HCF(765,1) .
