HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 81, 189, 614 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 81, 189, 614 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 81, 189, 614 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 81, 189, 614 is 1.
HCF(81, 189, 614) = 1
HCF of 81, 189, 614 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 81, 189, 614 is 1.
Highest Common Factor of 81,189,614 is 1
Step 1: Since 189 > 81, we apply the division lemma to 189 and 81, to get
189 = 81 x 2 + 27
Step 2: Since the reminder 81 ≠ 0, we apply division lemma to 27 and 81, to get
81 = 27 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 27, the HCF of 81 and 189 is 27
Notice that 27 = HCF(81,27) = HCF(189,81) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 614 > 27, we apply the division lemma to 614 and 27, to get
614 = 27 x 22 + 20
Step 2: Since the reminder 27 ≠ 0, we apply division lemma to 20 and 27, to get
27 = 20 x 1 + 7
Step 3: We consider the new divisor 20 and the new remainder 7, and apply the division lemma to get
20 = 7 x 2 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 27 and 614 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(20,7) = HCF(27,20) = HCF(614,27) .
