HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 994, 787, 617 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 994, 787, 617 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 994, 787, 617 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 994, 787, 617 is 1.

HCF(994, 787, 617) = 1

HCF of 994, 787, 617 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 994, 787, 617 is 1.

Highest Common Factor of 994,787,617 using Euclid's algorithm

Highest Common Factor of 994,787,617 is 1

Step 1: Since 994 > 787, we apply the division lemma to 994 and 787, to get

994 = 787 x 1 + 207

Step 2: Since the reminder 787 ≠ 0, we apply division lemma to 207 and 787, to get

787 = 207 x 3 + 166

Step 3: We consider the new divisor 207 and the new remainder 166, and apply the division lemma to get

207 = 166 x 1 + 41

We consider the new divisor 166 and the new remainder 41,and apply the division lemma to get

166 = 41 x 4 + 2

We consider the new divisor 41 and the new remainder 2,and apply the division lemma to get

41 = 2 x 20 + 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 994 and 787 is 1

Notice that 1 = HCF(2,1) = HCF(41,2) = HCF(166,41) = HCF(207,166) = HCF(787,207) = HCF(994,787) .

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

Step 1: Since 617 > 1, we apply the division lemma to 617 and 1, to get

617 = 1 x 617 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 617 is 1

Notice that 1 = HCF(617,1) .
