HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 813, 8383 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 813, 8383 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 813, 8383 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 813, 8383 is 1.
HCF(813, 8383) = 1
HCF of 813, 8383 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 813, 8383 is 1.
Highest Common Factor of 813,8383 is 1
Step 1: Since 8383 > 813, we apply the division lemma to 8383 and 813, to get
8383 = 813 x 10 + 253
Step 2: Since the reminder 813 ≠ 0, we apply division lemma to 253 and 813, to get
813 = 253 x 3 + 54
Step 3: We consider the new divisor 253 and the new remainder 54, and apply the division lemma to get
253 = 54 x 4 + 37
We consider the new divisor 54 and the new remainder 37,and apply the division lemma to get
54 = 37 x 1 + 17
We consider the new divisor 37 and the new remainder 17,and apply the division lemma to get
37 = 17 x 2 + 3
We consider the new divisor 17 and the new remainder 3,and apply the division lemma to get
17 = 3 x 5 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 813 and 8383 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(17,3) = HCF(37,17) = HCF(54,37) = HCF(253,54) = HCF(813,253) = HCF(8383,813) .
