HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 810, 641, 906 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 810, 641, 906 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 810, 641, 906 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 810, 641, 906 is 1.

HCF(810, 641, 906) = 1

Highest common factor (HCF) of 810, 641, 906 is 1.

Highest Common Factor of 810,641,906 using Euclid's algorithm

Highest Common Factor of 810,641,906 is 1

Step 1: Since 810 > 641, we apply the division lemma to 810 and 641, to get

810 = 641 x 1 + 169

Step 2: Since the reminder 641 ≠ 0, we apply division lemma to 169 and 641, to get

641 = 169 x 3 + 134

Step 3: We consider the new divisor 169 and the new remainder 134, and apply the division lemma to get

169 = 134 x 1 + 35

We consider the new divisor 134 and the new remainder 35,and apply the division lemma to get

134 = 35 x 3 + 29

We consider the new divisor 35 and the new remainder 29,and apply the division lemma to get

35 = 29 x 1 + 6

We consider the new divisor 29 and the new remainder 6,and apply the division lemma to get

29 = 6 x 4 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 810 and 641 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(29,6) = HCF(35,29) = HCF(134,35) = HCF(169,134) = HCF(641,169) = HCF(810,641) .

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

Step 1: Since 906 > 1, we apply the division lemma to 906 and 1, to get

906 = 1 x 906 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 906 is 1

Notice that 1 = HCF(906,1) .
