HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 189, 6717, 2637 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 189, 6717, 2637 is 3 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 189, 6717, 2637 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 189, 6717, 2637 is 3.
HCF(189, 6717, 2637) = 3
HCF of 189, 6717, 2637 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 189, 6717, 2637 is 3.
Highest Common Factor of 189,6717,2637 is 3
Step 1: Since 6717 > 189, we apply the division lemma to 6717 and 189, to get
6717 = 189 x 35 + 102
Step 2: Since the reminder 189 ≠ 0, we apply division lemma to 102 and 189, to get
189 = 102 x 1 + 87
Step 3: We consider the new divisor 102 and the new remainder 87, and apply the division lemma to get
102 = 87 x 1 + 15
We consider the new divisor 87 and the new remainder 15,and apply the division lemma to get
87 = 15 x 5 + 12
We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get
15 = 12 x 1 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 189 and 6717 is 3
Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(87,15) = HCF(102,87) = HCF(189,102) = HCF(6717,189) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 2637 > 3, we apply the division lemma to 2637 and 3, to get
2637 = 3 x 879 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 2637 is 3
Notice that 3 = HCF(2637,3) .
