HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 641, 227, 641 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 641, 227, 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 641, 227, 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 641, 227, 641 is 1.

HCF(641, 227, 641) = 1

Highest common factor (HCF) of 641, 227, 641 is 1.

Highest Common Factor of 641,227,641 using Euclid's algorithm

Highest Common Factor of 641,227,641 is 1

Step 1: Since 641 > 227, we apply the division lemma to 641 and 227, to get

641 = 227 x 2 + 187

Step 2: Since the reminder 227 ≠ 0, we apply division lemma to 187 and 227, to get

227 = 187 x 1 + 40

Step 3: We consider the new divisor 187 and the new remainder 40, and apply the division lemma to get

187 = 40 x 4 + 27

We consider the new divisor 40 and the new remainder 27,and apply the division lemma to get

40 = 27 x 1 + 13

We consider the new divisor 27 and the new remainder 13,and apply the division lemma to get

27 = 13 x 2 + 1

We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get

13 = 1 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 641 and 227 is 1

Notice that 1 = HCF(13,1) = HCF(27,13) = HCF(40,27) = HCF(187,40) = HCF(227,187) = HCF(641,227) .

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

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

641 = 1 x 641 + 0

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

Notice that 1 = HCF(641,1) .
