HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 814, 543, 306 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 814, 543, 306 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 814, 543, 306 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 814, 543, 306 is 1.
HCF(814, 543, 306) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 814, 543, 306 is 1.
Step 1: Since 814 > 543, we apply the division lemma to 814 and 543, to get
814 = 543 x 1 + 271
Step 2: Since the reminder 543 ≠ 0, we apply division lemma to 271 and 543, to get
543 = 271 x 2 + 1
Step 3: We consider the new divisor 271 and the new remainder 1, and apply the division lemma to get
271 = 1 x 271 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 814 and 543 is 1
Notice that 1 = HCF(271,1) = HCF(543,271) = HCF(814,543) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 306 > 1, we apply the division lemma to 306 and 1, to get
306 = 1 x 306 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 306 is 1
Notice that 1 = HCF(306,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
