HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 503, 211 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 503, 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 503, 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 503, 211 is 1.
HCF(503, 211) = 1
HCF of 503, 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 503, 211 is 1.
Highest Common Factor of 503,211 is 1
Step 1: Since 503 > 211, we apply the division lemma to 503 and 211, to get
503 = 211 x 2 + 81
Step 2: Since the reminder 211 ≠ 0, we apply division lemma to 81 and 211, to get
211 = 81 x 2 + 49
Step 3: We consider the new divisor 81 and the new remainder 49, and apply the division lemma to get
81 = 49 x 1 + 32
We consider the new divisor 49 and the new remainder 32,and apply the division lemma to get
49 = 32 x 1 + 17
We consider the new divisor 32 and the new remainder 17,and apply the division lemma to get
32 = 17 x 1 + 15
We consider the new divisor 17 and the new remainder 15,and apply the division lemma to get
17 = 15 x 1 + 2
We consider the new divisor 15 and the new remainder 2,and apply the division lemma to get
15 = 2 x 7 + 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 503 and 211 is 1
Notice that 1 = HCF(2,1) = HCF(15,2) = HCF(17,15) = HCF(32,17) = HCF(49,32) = HCF(81,49) = HCF(211,81) = HCF(503,211) .
