HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 811, 457 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 811, 457 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, 457 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, 457 is 1.
HCF(811, 457) = 1
HCF of 811, 457 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, 457 is 1.
Highest Common Factor of 811,457 is 1
Step 1: Since 811 > 457, we apply the division lemma to 811 and 457, to get
811 = 457 x 1 + 354
Step 2: Since the reminder 457 ≠ 0, we apply division lemma to 354 and 457, to get
457 = 354 x 1 + 103
Step 3: We consider the new divisor 354 and the new remainder 103, and apply the division lemma to get
354 = 103 x 3 + 45
We consider the new divisor 103 and the new remainder 45,and apply the division lemma to get
103 = 45 x 2 + 13
We consider the new divisor 45 and the new remainder 13,and apply the division lemma to get
45 = 13 x 3 + 6
We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get
13 = 6 x 2 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 811 and 457 is 1
Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(45,13) = HCF(103,45) = HCF(354,103) = HCF(457,354) = HCF(811,457) .
