HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 891, 71 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 891, 71 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 891, 71 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 891, 71 is 1.
HCF(891, 71) = 1
HCF of 891, 71 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 891, 71 is 1.
Highest Common Factor of 891,71 is 1
Step 1: Since 891 > 71, we apply the division lemma to 891 and 71, to get
891 = 71 x 12 + 39
Step 2: Since the reminder 71 ≠ 0, we apply division lemma to 39 and 71, to get
71 = 39 x 1 + 32
Step 3: We consider the new divisor 39 and the new remainder 32, and apply the division lemma to get
39 = 32 x 1 + 7
We consider the new divisor 32 and the new remainder 7,and apply the division lemma to get
32 = 7 x 4 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 891 and 71 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(32,7) = HCF(39,32) = HCF(71,39) = HCF(891,71) .
