HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 811, 5530 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 811, 5530 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 811, 5530 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 811, 5530 is 1.
HCF(811, 5530) = 1
HCF of 811, 5530 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 811, 5530 is 1.
Highest Common Factor of 811,5530 is 1
Step 1: Since 5530 > 811, we apply the division lemma to 5530 and 811, to get
5530 = 811 x 6 + 664
Step 2: Since the reminder 811 ≠ 0, we apply division lemma to 664 and 811, to get
811 = 664 x 1 + 147
Step 3: We consider the new divisor 664 and the new remainder 147, and apply the division lemma to get
664 = 147 x 4 + 76
We consider the new divisor 147 and the new remainder 76,and apply the division lemma to get
147 = 76 x 1 + 71
We consider the new divisor 76 and the new remainder 71,and apply the division lemma to get
76 = 71 x 1 + 5
We consider the new divisor 71 and the new remainder 5,and apply the division lemma to get
71 = 5 x 14 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 811 and 5530 is 1
Notice that 1 = HCF(5,1) = HCF(71,5) = HCF(76,71) = HCF(147,76) = HCF(664,147) = HCF(811,664) = HCF(5530,811) .
