HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 686, 723, 267 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 686, 723, 267 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 686, 723, 267 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 686, 723, 267 is 1.

HCF(686, 723, 267) = 1

HCF of 686, 723, 267 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 686, 723, 267 is 1.

Highest Common Factor of 686,723,267 using Euclid's algorithm

Highest Common Factor of 686,723,267 is 1

Step 1: Since 723 > 686, we apply the division lemma to 723 and 686, to get

723 = 686 x 1 + 37

Step 2: Since the reminder 686 ≠ 0, we apply division lemma to 37 and 686, to get

686 = 37 x 18 + 20

Step 3: We consider the new divisor 37 and the new remainder 20, and apply the division lemma to get

37 = 20 x 1 + 17

We consider the new divisor 20 and the new remainder 17,and apply the division lemma to get

20 = 17 x 1 + 3

We consider the new divisor 17 and the new remainder 3,and apply the division lemma to get

17 = 3 x 5 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 686 and 723 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(17,3) = HCF(20,17) = HCF(37,20) = HCF(686,37) = HCF(723,686) .

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

Step 1: Since 267 > 1, we apply the division lemma to 267 and 1, to get

267 = 1 x 267 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 267 is 1

Notice that 1 = HCF(267,1) .
