HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 441, 713, 191 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 441, 713, 191 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 441, 713, 191 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 441, 713, 191 is 1.

HCF(441, 713, 191) = 1

Highest common factor (HCF) of 441, 713, 191 is 1.

Highest Common Factor of 441,713,191 using Euclid's algorithm

Highest Common Factor of 441,713,191 is 1

Step 1: Since 713 > 441, we apply the division lemma to 713 and 441, to get

713 = 441 x 1 + 272

Step 2: Since the reminder 441 ≠ 0, we apply division lemma to 272 and 441, to get

441 = 272 x 1 + 169

Step 3: We consider the new divisor 272 and the new remainder 169, and apply the division lemma to get

272 = 169 x 1 + 103

We consider the new divisor 169 and the new remainder 103,and apply the division lemma to get

169 = 103 x 1 + 66

We consider the new divisor 103 and the new remainder 66,and apply the division lemma to get

103 = 66 x 1 + 37

We consider the new divisor 66 and the new remainder 37,and apply the division lemma to get

66 = 37 x 1 + 29

We consider the new divisor 37 and the new remainder 29,and apply the division lemma to get

37 = 29 x 1 + 8

We consider the new divisor 29 and the new remainder 8,and apply the division lemma to get

29 = 8 x 3 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 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 441 and 713 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(29,8) = HCF(37,29) = HCF(66,37) = HCF(103,66) = HCF(169,103) = HCF(272,169) = HCF(441,272) = HCF(713,441) .

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

Step 1: Since 191 > 1, we apply the division lemma to 191 and 1, to get

191 = 1 x 191 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 191 is 1

Notice that 1 = HCF(191,1) .
