HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 843, 641 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 843, 641 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 843, 641 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 843, 641 is 1.

HCF(843, 641) = 1

Highest common factor (HCF) of 843, 641 is 1.

Highest Common Factor of 843,641 using Euclid's algorithm

Highest Common Factor of 843,641 is 1

Step 1: Since 843 > 641, we apply the division lemma to 843 and 641, to get

843 = 641 x 1 + 202

Step 2: Since the reminder 641 ≠ 0, we apply division lemma to 202 and 641, to get

641 = 202 x 3 + 35

Step 3: We consider the new divisor 202 and the new remainder 35, and apply the division lemma to get

202 = 35 x 5 + 27

We consider the new divisor 35 and the new remainder 27,and apply the division lemma to get

35 = 27 x 1 + 8

We consider the new divisor 27 and the new remainder 8,and apply the division lemma to get

27 = 8 x 3 + 3

We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get

8 = 3 x 2 + 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 843 and 641 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(27,8) = HCF(35,27) = HCF(202,35) = HCF(641,202) = HCF(843,641) .
