HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 871, 517, 972 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 871, 517, 972 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 871, 517, 972 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 871, 517, 972 is 1.

HCF(871, 517, 972) = 1

HCF of 871, 517, 972 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 871, 517, 972 is 1.

Highest Common Factor of 871,517,972 using Euclid's algorithm

Highest Common Factor of 871,517,972 is 1

Step 1: Since 871 > 517, we apply the division lemma to 871 and 517, to get

871 = 517 x 1 + 354

Step 2: Since the reminder 517 ≠ 0, we apply division lemma to 354 and 517, to get

517 = 354 x 1 + 163

Step 3: We consider the new divisor 354 and the new remainder 163, and apply the division lemma to get

354 = 163 x 2 + 28

We consider the new divisor 163 and the new remainder 28,and apply the division lemma to get

163 = 28 x 5 + 23

We consider the new divisor 28 and the new remainder 23,and apply the division lemma to get

28 = 23 x 1 + 5

We consider the new divisor 23 and the new remainder 5,and apply the division lemma to get

23 = 5 x 4 + 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 871 and 517 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(23,5) = HCF(28,23) = HCF(163,28) = HCF(354,163) = HCF(517,354) = HCF(871,517) .

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

Step 1: Since 972 > 1, we apply the division lemma to 972 and 1, to get

972 = 1 x 972 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 972 is 1

Notice that 1 = HCF(972,1) .
