HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 997, 96489 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 997, 96489 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 997, 96489 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 997, 96489 is 1.
HCF(997, 96489) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 997, 96489 is 1.
Step 1: Since 96489 > 997, we apply the division lemma to 96489 and 997, to get
96489 = 997 x 96 + 777
Step 2: Since the reminder 997 ≠ 0, we apply division lemma to 777 and 997, to get
997 = 777 x 1 + 220
Step 3: We consider the new divisor 777 and the new remainder 220, and apply the division lemma to get
777 = 220 x 3 + 117
We consider the new divisor 220 and the new remainder 117,and apply the division lemma to get
220 = 117 x 1 + 103
We consider the new divisor 117 and the new remainder 103,and apply the division lemma to get
117 = 103 x 1 + 14
We consider the new divisor 103 and the new remainder 14,and apply the division lemma to get
103 = 14 x 7 + 5
We consider the new divisor 14 and the new remainder 5,and apply the division lemma to get
14 = 5 x 2 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 997 and 96489 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(103,14) = HCF(117,103) = HCF(220,117) = HCF(777,220) = HCF(997,777) = HCF(96489,997) .
Here are some samples of HCF using Euclid's Algorithm calculations.
