HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 863, 81271 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 863, 81271 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 863, 81271 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 863, 81271 is 1.
HCF(863, 81271) = 1
HCF of 863, 81271 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 863, 81271 is 1.
Highest Common Factor of 863,81271 is 1
Step 1: Since 81271 > 863, we apply the division lemma to 81271 and 863, to get
81271 = 863 x 94 + 149
Step 2: Since the reminder 863 ≠ 0, we apply division lemma to 149 and 863, to get
863 = 149 x 5 + 118
Step 3: We consider the new divisor 149 and the new remainder 118, and apply the division lemma to get
149 = 118 x 1 + 31
We consider the new divisor 118 and the new remainder 31,and apply the division lemma to get
118 = 31 x 3 + 25
We consider the new divisor 31 and the new remainder 25,and apply the division lemma to get
31 = 25 x 1 + 6
We consider the new divisor 25 and the new remainder 6,and apply the division lemma to get
25 = 6 x 4 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 863 and 81271 is 1
Notice that 1 = HCF(6,1) = HCF(25,6) = HCF(31,25) = HCF(118,31) = HCF(149,118) = HCF(863,149) = HCF(81271,863) .
