HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 873, 937, 690 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 873, 937, 690 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 873, 937, 690 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 873, 937, 690 is 1.

HCF(873, 937, 690) = 1

HCF of 873, 937, 690 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 873, 937, 690 is 1.

Highest Common Factor of 873,937,690 using Euclid's algorithm

Highest Common Factor of 873,937,690 is 1

Step 1: Since 937 > 873, we apply the division lemma to 937 and 873, to get

937 = 873 x 1 + 64

Step 2: Since the reminder 873 ≠ 0, we apply division lemma to 64 and 873, to get

873 = 64 x 13 + 41

Step 3: We consider the new divisor 64 and the new remainder 41, and apply the division lemma to get

64 = 41 x 1 + 23

We consider the new divisor 41 and the new remainder 23,and apply the division lemma to get

41 = 23 x 1 + 18

We consider the new divisor 23 and the new remainder 18,and apply the division lemma to get

23 = 18 x 1 + 5

We consider the new divisor 18 and the new remainder 5,and apply the division lemma to get

18 = 5 x 3 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 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 873 and 937 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(18,5) = HCF(23,18) = HCF(41,23) = HCF(64,41) = HCF(873,64) = HCF(937,873) .

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

Step 1: Since 690 > 1, we apply the division lemma to 690 and 1, to get

690 = 1 x 690 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 690 is 1

Notice that 1 = HCF(690,1) .
