HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 871, 647 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 871, 647 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, 647 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, 647 is 1.

HCF(871, 647) = 1

Highest common factor (HCF) of 871, 647 is 1.

Highest Common Factor of 871,647 using Euclid's algorithm

Highest Common Factor of 871,647 is 1

Step 1: Since 871 > 647, we apply the division lemma to 871 and 647, to get

871 = 647 x 1 + 224

Step 2: Since the reminder 647 ≠ 0, we apply division lemma to 224 and 647, to get

647 = 224 x 2 + 199

Step 3: We consider the new divisor 224 and the new remainder 199, and apply the division lemma to get

224 = 199 x 1 + 25

We consider the new divisor 199 and the new remainder 25,and apply the division lemma to get

199 = 25 x 7 + 24

We consider the new divisor 25 and the new remainder 24,and apply the division lemma to get

25 = 24 x 1 + 1

We consider the new divisor 24 and the new remainder 1,and apply the division lemma to get

24 = 1 x 24 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 871 and 647 is 1

Notice that 1 = HCF(24,1) = HCF(25,24) = HCF(199,25) = HCF(224,199) = HCF(647,224) = HCF(871,647) .
