HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 71, 38, 471 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 71, 38, 471 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 71, 38, 471 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 71, 38, 471 is 1.
HCF(71, 38, 471) = 1
HCF of 71, 38, 471 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 71, 38, 471 is 1.
Highest Common Factor of 71,38,471 is 1
Step 1: Since 71 > 38, we apply the division lemma to 71 and 38, to get
71 = 38 x 1 + 33
Step 2: Since the reminder 38 ≠ 0, we apply division lemma to 33 and 38, to get
38 = 33 x 1 + 5
Step 3: We consider the new divisor 33 and the new remainder 5, and apply the division lemma to get
33 = 5 x 6 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 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 71 and 38 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(33,5) = HCF(38,33) = HCF(71,38) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 471 > 1, we apply the division lemma to 471 and 1, to get
471 = 1 x 471 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 471 is 1
Notice that 1 = HCF(471,1) .
