HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 845, 334, 806 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 845, 334, 806 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 845, 334, 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 845, 334, 806 is 1.

HCF(845, 334, 806) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 845, 334, 806 is 1.

Highest Common Factor of 845,334,806 using Euclid's algorithm

Highest Common Factor of 845,334,806 is 1

Step 1: Since 845 > 334, we apply the division lemma to 845 and 334, to get

845 = 334 x 2 + 177

Step 2: Since the reminder 334 ≠ 0, we apply division lemma to 177 and 334, to get

334 = 177 x 1 + 157

Step 3: We consider the new divisor 177 and the new remainder 157, and apply the division lemma to get

177 = 157 x 1 + 20

We consider the new divisor 157 and the new remainder 20,and apply the division lemma to get

157 = 20 x 7 + 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 845 and 334 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(17,3) = HCF(20,17) = HCF(157,20) = HCF(177,157) = HCF(334,177) = HCF(845,334) .

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

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

806 = 1 x 806 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 806 is 1

Notice that 1 = HCF(806,1) .
