HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 8391, 4091 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 8391, 4091 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 8391, 4091 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 8391, 4091 is 1.
HCF(8391, 4091) = 1
HCF of 8391, 4091 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 8391, 4091 is 1.
Highest Common Factor of 8391,4091 is 1
Step 1: Since 8391 > 4091, we apply the division lemma to 8391 and 4091, to get
8391 = 4091 x 2 + 209
Step 2: Since the reminder 4091 ≠ 0, we apply division lemma to 209 and 4091, to get
4091 = 209 x 19 + 120
Step 3: We consider the new divisor 209 and the new remainder 120, and apply the division lemma to get
209 = 120 x 1 + 89
We consider the new divisor 120 and the new remainder 89,and apply the division lemma to get
120 = 89 x 1 + 31
We consider the new divisor 89 and the new remainder 31,and apply the division lemma to get
89 = 31 x 2 + 27
We consider the new divisor 31 and the new remainder 27,and apply the division lemma to get
31 = 27 x 1 + 4
We consider the new divisor 27 and the new remainder 4,and apply the division lemma to get
27 = 4 x 6 + 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 8391 and 4091 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(27,4) = HCF(31,27) = HCF(89,31) = HCF(120,89) = HCF(209,120) = HCF(4091,209) = HCF(8391,4091) .
