HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 6967, 2811, 61749 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 6967, 2811, 61749 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 6967, 2811, 61749 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 6967, 2811, 61749 is 1.
HCF(6967, 2811, 61749) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 6967, 2811, 61749 is 1.
Step 1: Since 6967 > 2811, we apply the division lemma to 6967 and 2811, to get
6967 = 2811 x 2 + 1345
Step 2: Since the reminder 2811 ≠ 0, we apply division lemma to 1345 and 2811, to get
2811 = 1345 x 2 + 121
Step 3: We consider the new divisor 1345 and the new remainder 121, and apply the division lemma to get
1345 = 121 x 11 + 14
We consider the new divisor 121 and the new remainder 14,and apply the division lemma to get
121 = 14 x 8 + 9
We consider the new divisor 14 and the new remainder 9,and apply the division lemma to get
14 = 9 x 1 + 5
We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get
9 = 5 x 1 + 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 6967 and 2811 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(14,9) = HCF(121,14) = HCF(1345,121) = HCF(2811,1345) = HCF(6967,2811) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 61749 > 1, we apply the division lemma to 61749 and 1, to get
61749 = 1 x 61749 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 61749 is 1
Notice that 1 = HCF(61749,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
