HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 971, 409, 801 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 971, 409, 801 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 971, 409, 801 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 971, 409, 801 is 1.

HCF(971, 409, 801) = 1

Highest common factor (HCF) of 971, 409, 801 is 1.

Highest Common Factor of 971,409,801 using Euclid's algorithm

Highest Common Factor of 971,409,801 is 1

Step 1: Since 971 > 409, we apply the division lemma to 971 and 409, to get

971 = 409 x 2 + 153

Step 2: Since the reminder 409 ≠ 0, we apply division lemma to 153 and 409, to get

409 = 153 x 2 + 103

Step 3: We consider the new divisor 153 and the new remainder 103, and apply the division lemma to get

153 = 103 x 1 + 50

We consider the new divisor 103 and the new remainder 50,and apply the division lemma to get

103 = 50 x 2 + 3

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

50 = 3 x 16 + 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 971 and 409 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(50,3) = HCF(103,50) = HCF(153,103) = HCF(409,153) = HCF(971,409) .

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

Step 1: Since 801 > 1, we apply the division lemma to 801 and 1, to get

801 = 1 x 801 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 801 is 1

Notice that 1 = HCF(801,1) .
