HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 758, 441, 398 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 758, 441, 398 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 758, 441, 398 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 758, 441, 398 is 1.

HCF(758, 441, 398) = 1

HCF of 758, 441, 398 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 758, 441, 398 is 1.

Highest Common Factor of 758,441,398 using Euclid's algorithm

Highest Common Factor of 758,441,398 is 1

Step 1: Since 758 > 441, we apply the division lemma to 758 and 441, to get

758 = 441 x 1 + 317

Step 2: Since the reminder 441 ≠ 0, we apply division lemma to 317 and 441, to get

441 = 317 x 1 + 124

Step 3: We consider the new divisor 317 and the new remainder 124, and apply the division lemma to get

317 = 124 x 2 + 69

We consider the new divisor 124 and the new remainder 69,and apply the division lemma to get

124 = 69 x 1 + 55

We consider the new divisor 69 and the new remainder 55,and apply the division lemma to get

69 = 55 x 1 + 14

We consider the new divisor 55 and the new remainder 14,and apply the division lemma to get

55 = 14 x 3 + 13

We consider the new divisor 14 and the new remainder 13,and apply the division lemma to get

14 = 13 x 1 + 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 758 and 441 is 1

Notice that 1 = HCF(13,1) = HCF(14,13) = HCF(55,14) = HCF(69,55) = HCF(124,69) = HCF(317,124) = HCF(441,317) = HCF(758,441) .

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

Step 1: Since 398 > 1, we apply the division lemma to 398 and 1, to get

398 = 1 x 398 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 398 is 1

Notice that 1 = HCF(398,1) .
