HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 641, 913, 277 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 641, 913, 277 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, 913, 277 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, 913, 277 is 1.

HCF(641, 913, 277) = 1

HCF of 641, 913, 277 using Euclid's algorithm

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

Highest common factor (HCF) of 641, 913, 277 is 1.

Highest Common Factor of 641,913,277 using Euclid's algorithm

Highest Common Factor of 641,913,277 is 1

Step 1: Since 913 > 641, we apply the division lemma to 913 and 641, to get

913 = 641 x 1 + 272

Step 2: Since the reminder 641 ≠ 0, we apply division lemma to 272 and 641, to get

641 = 272 x 2 + 97

Step 3: We consider the new divisor 272 and the new remainder 97, and apply the division lemma to get

272 = 97 x 2 + 78

We consider the new divisor 97 and the new remainder 78,and apply the division lemma to get

97 = 78 x 1 + 19

We consider the new divisor 78 and the new remainder 19,and apply the division lemma to get

78 = 19 x 4 + 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 641 and 913 is 1

Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(78,19) = HCF(97,78) = HCF(272,97) = HCF(641,272) = HCF(913,641) .

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

Step 1: Since 277 > 1, we apply the division lemma to 277 and 1, to get

277 = 1 x 277 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 277 is 1

Notice that 1 = HCF(277,1) .
