HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 617, 785, 372 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 617, 785, 372 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 617, 785, 372 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 617, 785, 372 is 1.

HCF(617, 785, 372) = 1

HCF of 617, 785, 372 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 617, 785, 372 is 1.

Highest Common Factor of 617,785,372 using Euclid's algorithm

Highest Common Factor of 617,785,372 is 1

Step 1: Since 785 > 617, we apply the division lemma to 785 and 617, to get

785 = 617 x 1 + 168

Step 2: Since the reminder 617 ≠ 0, we apply division lemma to 168 and 617, to get

617 = 168 x 3 + 113

Step 3: We consider the new divisor 168 and the new remainder 113, and apply the division lemma to get

168 = 113 x 1 + 55

We consider the new divisor 113 and the new remainder 55,and apply the division lemma to get

113 = 55 x 2 + 3

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

55 = 3 x 18 + 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 617 and 785 is 1

Notice that 1 = HCF(3,1) = HCF(55,3) = HCF(113,55) = HCF(168,113) = HCF(617,168) = HCF(785,617) .

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

Step 1: Since 372 > 1, we apply the division lemma to 372 and 1, to get

372 = 1 x 372 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 372 is 1

Notice that 1 = HCF(372,1) .
