HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 382, 7917, 9981 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 382, 7917, 9981 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 382, 7917, 9981 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 382, 7917, 9981 is 1.
HCF(382, 7917, 9981) = 1
HCF of 382, 7917, 9981 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 382, 7917, 9981 is 1.
Highest Common Factor of 382,7917,9981 is 1
Step 1: Since 7917 > 382, we apply the division lemma to 7917 and 382, to get
7917 = 382 x 20 + 277
Step 2: Since the reminder 382 ≠ 0, we apply division lemma to 277 and 382, to get
382 = 277 x 1 + 105
Step 3: We consider the new divisor 277 and the new remainder 105, and apply the division lemma to get
277 = 105 x 2 + 67
We consider the new divisor 105 and the new remainder 67,and apply the division lemma to get
105 = 67 x 1 + 38
We consider the new divisor 67 and the new remainder 38,and apply the division lemma to get
67 = 38 x 1 + 29
We consider the new divisor 38 and the new remainder 29,and apply the division lemma to get
38 = 29 x 1 + 9
We consider the new divisor 29 and the new remainder 9,and apply the division lemma to get
29 = 9 x 3 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 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 382 and 7917 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(29,9) = HCF(38,29) = HCF(67,38) = HCF(105,67) = HCF(277,105) = HCF(382,277) = HCF(7917,382) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 9981 > 1, we apply the division lemma to 9981 and 1, to get
9981 = 1 x 9981 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 9981 is 1
Notice that 1 = HCF(9981,1) .
