HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 971, 571 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 971, 571 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 971, 571 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 971, 571 is 1.
HCF(971, 571) = 1
HCF of 971, 571 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 971, 571 is 1.
Highest Common Factor of 971,571 is 1
Step 1: Since 971 > 571, we apply the division lemma to 971 and 571, to get
971 = 571 x 1 + 400
Step 2: Since the reminder 571 ≠ 0, we apply division lemma to 400 and 571, to get
571 = 400 x 1 + 171
Step 3: We consider the new divisor 400 and the new remainder 171, and apply the division lemma to get
400 = 171 x 2 + 58
We consider the new divisor 171 and the new remainder 58,and apply the division lemma to get
171 = 58 x 2 + 55
We consider the new divisor 58 and the new remainder 55,and apply the division lemma to get
58 = 55 x 1 + 3
We consider the new divisor 55 and the new remainder 3,and apply the division lemma to get
55 = 3 x 18 + 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 971 and 571 is 1
Notice that 1 = HCF(3,1) = HCF(55,3) = HCF(58,55) = HCF(171,58) = HCF(400,171) = HCF(571,400) = HCF(971,571) .
