HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 571, 191 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 571, 191 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 571, 191 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 571, 191 is 1.
HCF(571, 191) = 1
HCF of 571, 191 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 571, 191 is 1.
Highest Common Factor of 571,191 is 1
Step 1: Since 571 > 191, we apply the division lemma to 571 and 191, to get
571 = 191 x 2 + 189
Step 2: Since the reminder 191 ≠ 0, we apply division lemma to 189 and 191, to get
191 = 189 x 1 + 2
Step 3: We consider the new divisor 189 and the new remainder 2, and apply the division lemma to get
189 = 2 x 94 + 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 571 and 191 is 1
Notice that 1 = HCF(2,1) = HCF(189,2) = HCF(191,189) = HCF(571,191) .
