HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 342, 543, 487 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 342, 543, 487 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 342, 543, 487 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 342, 543, 487 is 1.
HCF(342, 543, 487) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 342, 543, 487 is 1.
Step 1: Since 543 > 342, we apply the division lemma to 543 and 342, to get
543 = 342 x 1 + 201
Step 2: Since the reminder 342 ≠ 0, we apply division lemma to 201 and 342, to get
342 = 201 x 1 + 141
Step 3: We consider the new divisor 201 and the new remainder 141, and apply the division lemma to get
201 = 141 x 1 + 60
We consider the new divisor 141 and the new remainder 60,and apply the division lemma to get
141 = 60 x 2 + 21
We consider the new divisor 60 and the new remainder 21,and apply the division lemma to get
60 = 21 x 2 + 18
We consider the new divisor 21 and the new remainder 18,and apply the division lemma to get
21 = 18 x 1 + 3
We consider the new divisor 18 and the new remainder 3,and apply the division lemma to get
18 = 3 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 342 and 543 is 3
Notice that 3 = HCF(18,3) = HCF(21,18) = HCF(60,21) = HCF(141,60) = HCF(201,141) = HCF(342,201) = HCF(543,342) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 487 > 3, we apply the division lemma to 487 and 3, to get
487 = 3 x 162 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 487 is 1
Notice that 1 = HCF(3,1) = HCF(487,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
