HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 797, 871 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 797, 871 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 797, 871 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 797, 871 is 1.
HCF(797, 871) = 1
HCF of 797, 871 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 797, 871 is 1.
Highest Common Factor of 797,871 is 1
Step 1: Since 871 > 797, we apply the division lemma to 871 and 797, to get
871 = 797 x 1 + 74
Step 2: Since the reminder 797 ≠ 0, we apply division lemma to 74 and 797, to get
797 = 74 x 10 + 57
Step 3: We consider the new divisor 74 and the new remainder 57, and apply the division lemma to get
74 = 57 x 1 + 17
We consider the new divisor 57 and the new remainder 17,and apply the division lemma to get
57 = 17 x 3 + 6
We consider the new divisor 17 and the new remainder 6,and apply the division lemma to get
17 = 6 x 2 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 797 and 871 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(17,6) = HCF(57,17) = HCF(74,57) = HCF(797,74) = HCF(871,797) .
