HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 554, 940, 806 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 554, 940, 806 is 2 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 554, 940, 806 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 554, 940, 806 is 2.

HCF(554, 940, 806) = 2

HCF of 554, 940, 806 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 554, 940, 806 is 2.

Highest Common Factor of 554,940,806 using Euclid's algorithm

Highest Common Factor of 554,940,806 is 2

Step 1: Since 940 > 554, we apply the division lemma to 940 and 554, to get

940 = 554 x 1 + 386

Step 2: Since the reminder 554 ≠ 0, we apply division lemma to 386 and 554, to get

554 = 386 x 1 + 168

Step 3: We consider the new divisor 386 and the new remainder 168, and apply the division lemma to get

386 = 168 x 2 + 50

We consider the new divisor 168 and the new remainder 50,and apply the division lemma to get

168 = 50 x 3 + 18

We consider the new divisor 50 and the new remainder 18,and apply the division lemma to get

50 = 18 x 2 + 14

We consider the new divisor 18 and the new remainder 14,and apply the division lemma to get

18 = 14 x 1 + 4

We consider the new divisor 14 and the new remainder 4,and apply the division lemma to get

14 = 4 x 3 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 554 and 940 is 2

Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(18,14) = HCF(50,18) = HCF(168,50) = HCF(386,168) = HCF(554,386) = HCF(940,554) .

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

Step 1: Since 806 > 2, we apply the division lemma to 806 and 2, to get

806 = 2 x 403 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 806 is 2

Notice that 2 = HCF(806,2) .
