HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 517, 211 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 517, 211 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 517, 211 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 517, 211 is 1.
HCF(517, 211) = 1
HCF of 517, 211 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 517, 211 is 1.
Highest Common Factor of 517,211 is 1
Step 1: Since 517 > 211, we apply the division lemma to 517 and 211, to get
517 = 211 x 2 + 95
Step 2: Since the reminder 211 ≠ 0, we apply division lemma to 95 and 211, to get
211 = 95 x 2 + 21
Step 3: We consider the new divisor 95 and the new remainder 21, and apply the division lemma to get
95 = 21 x 4 + 11
We consider the new divisor 21 and the new remainder 11,and apply the division lemma to get
21 = 11 x 1 + 10
We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get
11 = 10 x 1 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 517 and 211 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(21,11) = HCF(95,21) = HCF(211,95) = HCF(517,211) .
