HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 691, 583, 968 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 691, 583, 968 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 691, 583, 968 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 691, 583, 968 is 1.

HCF(691, 583, 968) = 1

HCF of 691, 583, 968 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 691, 583, 968 is 1.

Highest Common Factor of 691,583,968 using Euclid's algorithm

Highest Common Factor of 691,583,968 is 1

Step 1: Since 691 > 583, we apply the division lemma to 691 and 583, to get

691 = 583 x 1 + 108

Step 2: Since the reminder 583 ≠ 0, we apply division lemma to 108 and 583, to get

583 = 108 x 5 + 43

Step 3: We consider the new divisor 108 and the new remainder 43, and apply the division lemma to get

108 = 43 x 2 + 22

We consider the new divisor 43 and the new remainder 22,and apply the division lemma to get

43 = 22 x 1 + 21

We consider the new divisor 22 and the new remainder 21,and apply the division lemma to get

22 = 21 x 1 + 1

We consider the new divisor 21 and the new remainder 1,and apply the division lemma to get

21 = 1 x 21 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 691 and 583 is 1

Notice that 1 = HCF(21,1) = HCF(22,21) = HCF(43,22) = HCF(108,43) = HCF(583,108) = HCF(691,583) .

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

Step 1: Since 968 > 1, we apply the division lemma to 968 and 1, to get

968 = 1 x 968 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 968 is 1

Notice that 1 = HCF(968,1) .
