HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 641, 838, 348 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 641, 838, 348 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, 838, 348 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, 838, 348 is 1.

HCF(641, 838, 348) = 1

HCF of 641, 838, 348 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 641, 838, 348 is 1.

Highest Common Factor of 641,838,348 using Euclid's algorithm

Highest Common Factor of 641,838,348 is 1

Step 1: Since 838 > 641, we apply the division lemma to 838 and 641, to get

838 = 641 x 1 + 197

Step 2: Since the reminder 641 ≠ 0, we apply division lemma to 197 and 641, to get

641 = 197 x 3 + 50

Step 3: We consider the new divisor 197 and the new remainder 50, and apply the division lemma to get

197 = 50 x 3 + 47

We consider the new divisor 50 and the new remainder 47,and apply the division lemma to get

50 = 47 x 1 + 3

We consider the new divisor 47 and the new remainder 3,and apply the division lemma to get

47 = 3 x 15 + 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 641 and 838 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(47,3) = HCF(50,47) = HCF(197,50) = HCF(641,197) = HCF(838,641) .

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

Step 1: Since 348 > 1, we apply the division lemma to 348 and 1, to get

348 = 1 x 348 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 348 is 1

Notice that 1 = HCF(348,1) .
