HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 671, 791, 401 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 671, 791, 401 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 671, 791, 401 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 671, 791, 401 is 1.

HCF(671, 791, 401) = 1

Highest common factor (HCF) of 671, 791, 401 is 1.

Highest Common Factor of 671,791,401 using Euclid's algorithm

Highest Common Factor of 671,791,401 is 1

Step 1: Since 791 > 671, we apply the division lemma to 791 and 671, to get

791 = 671 x 1 + 120

Step 2: Since the reminder 671 ≠ 0, we apply division lemma to 120 and 671, to get

671 = 120 x 5 + 71

Step 3: We consider the new divisor 120 and the new remainder 71, and apply the division lemma to get

120 = 71 x 1 + 49

We consider the new divisor 71 and the new remainder 49,and apply the division lemma to get

71 = 49 x 1 + 22

We consider the new divisor 49 and the new remainder 22,and apply the division lemma to get

49 = 22 x 2 + 5

We consider the new divisor 22 and the new remainder 5,and apply the division lemma to get

22 = 5 x 4 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 671 and 791 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(22,5) = HCF(49,22) = HCF(71,49) = HCF(120,71) = HCF(671,120) = HCF(791,671) .

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

Step 1: Since 401 > 1, we apply the division lemma to 401 and 1, to get

401 = 1 x 401 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 401 is 1

Notice that 1 = HCF(401,1) .
