HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 806, 634 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 806, 634 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 806, 634 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, 634 is 2.

HCF(806, 634) = 2

Highest common factor (HCF) of 806, 634 is 2.

Highest Common Factor of 806,634 using Euclid's algorithm

Highest Common Factor of 806,634 is 2

Step 1: Since 806 > 634, we apply the division lemma to 806 and 634, to get

806 = 634 x 1 + 172

Step 2: Since the reminder 634 ≠ 0, we apply division lemma to 172 and 634, to get

634 = 172 x 3 + 118

Step 3: We consider the new divisor 172 and the new remainder 118, and apply the division lemma to get

172 = 118 x 1 + 54

We consider the new divisor 118 and the new remainder 54,and apply the division lemma to get

118 = 54 x 2 + 10

We consider the new divisor 54 and the new remainder 10,and apply the division lemma to get

54 = 10 x 5 + 4

We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get

10 = 4 x 2 + 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 806 and 634 is 2

Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(54,10) = HCF(118,54) = HCF(172,118) = HCF(634,172) = HCF(806,634) .
