HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 978, 97081 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 978, 97081 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 978, 97081 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 978, 97081 is 1.
HCF(978, 97081) = 1
HCF of 978, 97081 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 978, 97081 is 1.
Highest Common Factor of 978,97081 is 1
Step 1: Since 97081 > 978, we apply the division lemma to 97081 and 978, to get
97081 = 978 x 99 + 259
Step 2: Since the reminder 978 ≠ 0, we apply division lemma to 259 and 978, to get
978 = 259 x 3 + 201
Step 3: We consider the new divisor 259 and the new remainder 201, and apply the division lemma to get
259 = 201 x 1 + 58
We consider the new divisor 201 and the new remainder 58,and apply the division lemma to get
201 = 58 x 3 + 27
We consider the new divisor 58 and the new remainder 27,and apply the division lemma to get
58 = 27 x 2 + 4
We consider the new divisor 27 and the new remainder 4,and apply the division lemma to get
27 = 4 x 6 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 978 and 97081 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(27,4) = HCF(58,27) = HCF(201,58) = HCF(259,201) = HCF(978,259) = HCF(97081,978) .
