HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 9817, 2215 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 9817, 2215 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 9817, 2215 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 9817, 2215 is 1.
HCF(9817, 2215) = 1
HCF of 9817, 2215 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 9817, 2215 is 1.
Highest Common Factor of 9817,2215 is 1
Step 1: Since 9817 > 2215, we apply the division lemma to 9817 and 2215, to get
9817 = 2215 x 4 + 957
Step 2: Since the reminder 2215 ≠ 0, we apply division lemma to 957 and 2215, to get
2215 = 957 x 2 + 301
Step 3: We consider the new divisor 957 and the new remainder 301, and apply the division lemma to get
957 = 301 x 3 + 54
We consider the new divisor 301 and the new remainder 54,and apply the division lemma to get
301 = 54 x 5 + 31
We consider the new divisor 54 and the new remainder 31,and apply the division lemma to get
54 = 31 x 1 + 23
We consider the new divisor 31 and the new remainder 23,and apply the division lemma to get
31 = 23 x 1 + 8
We consider the new divisor 23 and the new remainder 8,and apply the division lemma to get
23 = 8 x 2 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 9817 and 2215 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(23,8) = HCF(31,23) = HCF(54,31) = HCF(301,54) = HCF(957,301) = HCF(2215,957) = HCF(9817,2215) .
