HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 991, 597, 807 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 991, 597, 807 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 991, 597, 807 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 991, 597, 807 is 1.

HCF(991, 597, 807) = 1

HCF of 991, 597, 807 using Euclid's algorithm

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

Highest common factor (HCF) of 991, 597, 807 is 1.

Highest Common Factor of 991,597,807 using Euclid's algorithm

Highest Common Factor of 991,597,807 is 1

Step 1: Since 991 > 597, we apply the division lemma to 991 and 597, to get

991 = 597 x 1 + 394

Step 2: Since the reminder 597 ≠ 0, we apply division lemma to 394 and 597, to get

597 = 394 x 1 + 203

Step 3: We consider the new divisor 394 and the new remainder 203, and apply the division lemma to get

394 = 203 x 1 + 191

We consider the new divisor 203 and the new remainder 191,and apply the division lemma to get

203 = 191 x 1 + 12

We consider the new divisor 191 and the new remainder 12,and apply the division lemma to get

191 = 12 x 15 + 11

We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get

12 = 11 x 1 + 1

We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get

11 = 1 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 991 and 597 is 1

Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(191,12) = HCF(203,191) = HCF(394,203) = HCF(597,394) = HCF(991,597) .


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

Step 1: Since 807 > 1, we apply the division lemma to 807 and 1, to get

807 = 1 x 807 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 807 is 1

Notice that 1 = HCF(807,1) .
