HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 683, 891 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 683, 891 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 683, 891 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 683, 891 is 1.
HCF(683, 891) = 1
HCF of 683, 891 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 683, 891 is 1.
Highest Common Factor of 683,891 is 1
Step 1: Since 891 > 683, we apply the division lemma to 891 and 683, to get
891 = 683 x 1 + 208
Step 2: Since the reminder 683 ≠ 0, we apply division lemma to 208 and 683, to get
683 = 208 x 3 + 59
Step 3: We consider the new divisor 208 and the new remainder 59, and apply the division lemma to get
208 = 59 x 3 + 31
We consider the new divisor 59 and the new remainder 31,and apply the division lemma to get
59 = 31 x 1 + 28
We consider the new divisor 31 and the new remainder 28,and apply the division lemma to get
31 = 28 x 1 + 3
We consider the new divisor 28 and the new remainder 3,and apply the division lemma to get
28 = 3 x 9 + 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 683 and 891 is 1
Notice that 1 = HCF(3,1) = HCF(28,3) = HCF(31,28) = HCF(59,31) = HCF(208,59) = HCF(683,208) = HCF(891,683) .
