HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 217, 301 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 217, 301 is 7 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 217, 301 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 217, 301 is 7.
HCF(217, 301) = 7
HCF of 217, 301 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 217, 301 is 7.
Highest Common Factor of 217,301 is 7
Step 1: Since 301 > 217, we apply the division lemma to 301 and 217, to get
301 = 217 x 1 + 84
Step 2: Since the reminder 217 ≠ 0, we apply division lemma to 84 and 217, to get
217 = 84 x 2 + 49
Step 3: We consider the new divisor 84 and the new remainder 49, and apply the division lemma to get
84 = 49 x 1 + 35
We consider the new divisor 49 and the new remainder 35,and apply the division lemma to get
49 = 35 x 1 + 14
We consider the new divisor 35 and the new remainder 14,and apply the division lemma to get
35 = 14 x 2 + 7
We consider the new divisor 14 and the new remainder 7,and apply the division lemma to get
14 = 7 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 217 and 301 is 7
Notice that 7 = HCF(14,7) = HCF(35,14) = HCF(49,35) = HCF(84,49) = HCF(217,84) = HCF(301,217) .
