HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 9731, 1865, 91432 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 9731, 1865, 91432 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 9731, 1865, 91432 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 9731, 1865, 91432 is 1.
HCF(9731, 1865, 91432) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 9731, 1865, 91432 is 1.
Step 1: Since 9731 > 1865, we apply the division lemma to 9731 and 1865, to get
9731 = 1865 x 5 + 406
Step 2: Since the reminder 1865 ≠ 0, we apply division lemma to 406 and 1865, to get
1865 = 406 x 4 + 241
Step 3: We consider the new divisor 406 and the new remainder 241, and apply the division lemma to get
406 = 241 x 1 + 165
We consider the new divisor 241 and the new remainder 165,and apply the division lemma to get
241 = 165 x 1 + 76
We consider the new divisor 165 and the new remainder 76,and apply the division lemma to get
165 = 76 x 2 + 13
We consider the new divisor 76 and the new remainder 13,and apply the division lemma to get
76 = 13 x 5 + 11
We consider the new divisor 13 and the new remainder 11,and apply the division lemma to get
13 = 11 x 1 + 2
We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get
11 = 2 x 5 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 9731 and 1865 is 1
Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(13,11) = HCF(76,13) = HCF(165,76) = HCF(241,165) = HCF(406,241) = HCF(1865,406) = HCF(9731,1865) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 91432 > 1, we apply the division lemma to 91432 and 1, to get
91432 = 1 x 91432 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 91432 is 1
Notice that 1 = HCF(91432,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
