HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 806, 2195 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 806, 2195 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 806, 2195 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 806, 2195 is 1.

HCF(806, 2195) = 1

Highest Common Factor of 806,2195 using Euclid's algorithm

Highest Common Factor of 806,2195 is 1

Step 1: Since 2195 > 806, we apply the division lemma to 2195 and 806, to get

2195 = 806 x 2 + 583

Step 2: Since the reminder 806 ≠ 0, we apply division lemma to 583 and 806, to get

806 = 583 x 1 + 223

Step 3: We consider the new divisor 583 and the new remainder 223, and apply the division lemma to get

583 = 223 x 2 + 137

We consider the new divisor 223 and the new remainder 137,and apply the division lemma to get

223 = 137 x 1 + 86

We consider the new divisor 137 and the new remainder 86,and apply the division lemma to get

137 = 86 x 1 + 51

We consider the new divisor 86 and the new remainder 51,and apply the division lemma to get

86 = 51 x 1 + 35

We consider the new divisor 51 and the new remainder 35,and apply the division lemma to get

51 = 35 x 1 + 16

We consider the new divisor 35 and the new remainder 16,and apply the division lemma to get

35 = 16 x 2 + 3

We consider the new divisor 16 and the new remainder 3,and apply the division lemma to get

16 = 3 x 5 + 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 806 and 2195 is 1

Notice that 1 = HCF(3,1) = HCF(16,3) = HCF(35,16) = HCF(51,35) = HCF(86,51) = HCF(137,86) = HCF(223,137) = HCF(583,223) = HCF(806,583) = HCF(2195,806) .
