HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 166, 809, 851 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 166, 809, 851 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 166, 809, 851 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 166, 809, 851 is 1.

HCF(166, 809, 851) = 1

HCF of 166, 809, 851 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 166, 809, 851 is 1.

Highest Common Factor of 166,809,851 using Euclid's algorithm

Highest Common Factor of 166,809,851 is 1

Step 1: Since 809 > 166, we apply the division lemma to 809 and 166, to get

809 = 166 x 4 + 145

Step 2: Since the reminder 166 ≠ 0, we apply division lemma to 145 and 166, to get

166 = 145 x 1 + 21

Step 3: We consider the new divisor 145 and the new remainder 21, and apply the division lemma to get

145 = 21 x 6 + 19

We consider the new divisor 21 and the new remainder 19,and apply the division lemma to get

21 = 19 x 1 + 2

We consider the new divisor 19 and the new remainder 2,and apply the division lemma to get

19 = 2 x 9 + 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 166 and 809 is 1

Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(21,19) = HCF(145,21) = HCF(166,145) = HCF(809,166) .

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

Step 1: Since 851 > 1, we apply the division lemma to 851 and 1, to get

851 = 1 x 851 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 851 is 1

Notice that 1 = HCF(851,1) .
