HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 861, 3966 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 861, 3966 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 861, 3966 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 861, 3966 is 3.
HCF(861, 3966) = 3
HCF of 861, 3966 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 861, 3966 is 3.
Highest Common Factor of 861,3966 is 3
Step 1: Since 3966 > 861, we apply the division lemma to 3966 and 861, to get
3966 = 861 x 4 + 522
Step 2: Since the reminder 861 ≠ 0, we apply division lemma to 522 and 861, to get
861 = 522 x 1 + 339
Step 3: We consider the new divisor 522 and the new remainder 339, and apply the division lemma to get
522 = 339 x 1 + 183
We consider the new divisor 339 and the new remainder 183,and apply the division lemma to get
339 = 183 x 1 + 156
We consider the new divisor 183 and the new remainder 156,and apply the division lemma to get
183 = 156 x 1 + 27
We consider the new divisor 156 and the new remainder 27,and apply the division lemma to get
156 = 27 x 5 + 21
We consider the new divisor 27 and the new remainder 21,and apply the division lemma to get
27 = 21 x 1 + 6
We consider the new divisor 21 and the new remainder 6,and apply the division lemma to get
21 = 6 x 3 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 861 and 3966 is 3
Notice that 3 = HCF(6,3) = HCF(21,6) = HCF(27,21) = HCF(156,27) = HCF(183,156) = HCF(339,183) = HCF(522,339) = HCF(861,522) = HCF(3966,861) .
