HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 831, 3891 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 831, 3891 is 3 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 831, 3891 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 831, 3891 is 3.
HCF(831, 3891) = 3
HCF of 831, 3891 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 831, 3891 is 3.
Highest Common Factor of 831,3891 is 3
Step 1: Since 3891 > 831, we apply the division lemma to 3891 and 831, to get
3891 = 831 x 4 + 567
Step 2: Since the reminder 831 ≠ 0, we apply division lemma to 567 and 831, to get
831 = 567 x 1 + 264
Step 3: We consider the new divisor 567 and the new remainder 264, and apply the division lemma to get
567 = 264 x 2 + 39
We consider the new divisor 264 and the new remainder 39,and apply the division lemma to get
264 = 39 x 6 + 30
We consider the new divisor 39 and the new remainder 30,and apply the division lemma to get
39 = 30 x 1 + 9
We consider the new divisor 30 and the new remainder 9,and apply the division lemma to get
30 = 9 x 3 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 831 and 3891 is 3
Notice that 3 = HCF(9,3) = HCF(30,9) = HCF(39,30) = HCF(264,39) = HCF(567,264) = HCF(831,567) = HCF(3891,831) .
