HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 891, 6686 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 891, 6686 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, 6686 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, 6686 is 1.
HCF(891, 6686) = 1
HCF of 891, 6686 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, 6686 is 1.
Highest Common Factor of 891,6686 is 1
Step 1: Since 6686 > 891, we apply the division lemma to 6686 and 891, to get
6686 = 891 x 7 + 449
Step 2: Since the reminder 891 ≠ 0, we apply division lemma to 449 and 891, to get
891 = 449 x 1 + 442
Step 3: We consider the new divisor 449 and the new remainder 442, and apply the division lemma to get
449 = 442 x 1 + 7
We consider the new divisor 442 and the new remainder 7,and apply the division lemma to get
442 = 7 x 63 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 891 and 6686 is 1
Notice that 1 = HCF(7,1) = HCF(442,7) = HCF(449,442) = HCF(891,449) = HCF(6686,891) .
