HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 891, 63956 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 891, 63956 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, 63956 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, 63956 is 1.
HCF(891, 63956) = 1
HCF of 891, 63956 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, 63956 is 1.
Highest Common Factor of 891,63956 is 1
Step 1: Since 63956 > 891, we apply the division lemma to 63956 and 891, to get
63956 = 891 x 71 + 695
Step 2: Since the reminder 891 ≠ 0, we apply division lemma to 695 and 891, to get
891 = 695 x 1 + 196
Step 3: We consider the new divisor 695 and the new remainder 196, and apply the division lemma to get
695 = 196 x 3 + 107
We consider the new divisor 196 and the new remainder 107,and apply the division lemma to get
196 = 107 x 1 + 89
We consider the new divisor 107 and the new remainder 89,and apply the division lemma to get
107 = 89 x 1 + 18
We consider the new divisor 89 and the new remainder 18,and apply the division lemma to get
89 = 18 x 4 + 17
We consider the new divisor 18 and the new remainder 17,and apply the division lemma to get
18 = 17 x 1 + 1
We consider the new divisor 17 and the new remainder 1,and apply the division lemma to get
17 = 1 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 891 and 63956 is 1
Notice that 1 = HCF(17,1) = HCF(18,17) = HCF(89,18) = HCF(107,89) = HCF(196,107) = HCF(695,196) = HCF(891,695) = HCF(63956,891) .
