HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 585, 691, 772 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 585, 691, 772 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 585, 691, 772 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 585, 691, 772 is 1.

HCF(585, 691, 772) = 1

HCF of 585, 691, 772 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 585, 691, 772 is 1.

Highest Common Factor of 585,691,772 using Euclid's algorithm

Highest Common Factor of 585,691,772 is 1

Step 1: Since 691 > 585, we apply the division lemma to 691 and 585, to get

691 = 585 x 1 + 106

Step 2: Since the reminder 585 ≠ 0, we apply division lemma to 106 and 585, to get

585 = 106 x 5 + 55

Step 3: We consider the new divisor 106 and the new remainder 55, and apply the division lemma to get

106 = 55 x 1 + 51

We consider the new divisor 55 and the new remainder 51,and apply the division lemma to get

55 = 51 x 1 + 4

We consider the new divisor 51 and the new remainder 4,and apply the division lemma to get

51 = 4 x 12 + 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 585 and 691 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(51,4) = HCF(55,51) = HCF(106,55) = HCF(585,106) = HCF(691,585) .

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

Step 1: Since 772 > 1, we apply the division lemma to 772 and 1, to get

772 = 1 x 772 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 772 is 1

Notice that 1 = HCF(772,1) .
