HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 3811, 7989 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 3811, 7989 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 3811, 7989 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 3811, 7989 is 1.
HCF(3811, 7989) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 3811, 7989 is 1.
Step 1: Since 7989 > 3811, we apply the division lemma to 7989 and 3811, to get
7989 = 3811 x 2 + 367
Step 2: Since the reminder 3811 ≠ 0, we apply division lemma to 367 and 3811, to get
3811 = 367 x 10 + 141
Step 3: We consider the new divisor 367 and the new remainder 141, and apply the division lemma to get
367 = 141 x 2 + 85
We consider the new divisor 141 and the new remainder 85,and apply the division lemma to get
141 = 85 x 1 + 56
We consider the new divisor 85 and the new remainder 56,and apply the division lemma to get
85 = 56 x 1 + 29
We consider the new divisor 56 and the new remainder 29,and apply the division lemma to get
56 = 29 x 1 + 27
We consider the new divisor 29 and the new remainder 27,and apply the division lemma to get
29 = 27 x 1 + 2
We consider the new divisor 27 and the new remainder 2,and apply the division lemma to get
27 = 2 x 13 + 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 3811 and 7989 is 1
Notice that 1 = HCF(2,1) = HCF(27,2) = HCF(29,27) = HCF(56,29) = HCF(85,56) = HCF(141,85) = HCF(367,141) = HCF(3811,367) = HCF(7989,3811) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
