HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 8217, 403 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 8217, 403 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 8217, 403 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 8217, 403 is 1.
HCF(8217, 403) = 1
HCF of 8217, 403 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 8217, 403 is 1.
Highest Common Factor of 8217,403 is 1
Step 1: Since 8217 > 403, we apply the division lemma to 8217 and 403, to get
8217 = 403 x 20 + 157
Step 2: Since the reminder 403 ≠ 0, we apply division lemma to 157 and 403, to get
403 = 157 x 2 + 89
Step 3: We consider the new divisor 157 and the new remainder 89, and apply the division lemma to get
157 = 89 x 1 + 68
We consider the new divisor 89 and the new remainder 68,and apply the division lemma to get
89 = 68 x 1 + 21
We consider the new divisor 68 and the new remainder 21,and apply the division lemma to get
68 = 21 x 3 + 5
We consider the new divisor 21 and the new remainder 5,and apply the division lemma to get
21 = 5 x 4 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 8217 and 403 is 1
Notice that 1 = HCF(5,1) = HCF(21,5) = HCF(68,21) = HCF(89,68) = HCF(157,89) = HCF(403,157) = HCF(8217,403) .
