HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 543, 886, 561 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 543, 886, 561 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 543, 886, 561 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 543, 886, 561 is 1.

HCF(543, 886, 561) = 1

HCF of 543, 886, 561 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 543, 886, 561 is 1.

Highest Common Factor of 543,886,561 using Euclid's algorithm

Highest Common Factor of 543,886,561 is 1

Step 1: Since 886 > 543, we apply the division lemma to 886 and 543, to get

886 = 543 x 1 + 343

Step 2: Since the reminder 543 ≠ 0, we apply division lemma to 343 and 543, to get

543 = 343 x 1 + 200

Step 3: We consider the new divisor 343 and the new remainder 200, and apply the division lemma to get

343 = 200 x 1 + 143

We consider the new divisor 200 and the new remainder 143,and apply the division lemma to get

200 = 143 x 1 + 57

We consider the new divisor 143 and the new remainder 57,and apply the division lemma to get

143 = 57 x 2 + 29

We consider the new divisor 57 and the new remainder 29,and apply the division lemma to get

57 = 29 x 1 + 28

We consider the new divisor 29 and the new remainder 28,and apply the division lemma to get

29 = 28 x 1 + 1

We consider the new divisor 28 and the new remainder 1,and apply the division lemma to get

28 = 1 x 28 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 543 and 886 is 1

Notice that 1 = HCF(28,1) = HCF(29,28) = HCF(57,29) = HCF(143,57) = HCF(200,143) = HCF(343,200) = HCF(543,343) = HCF(886,543) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 561 > 1, we apply the division lemma to 561 and 1, to get

561 = 1 x 561 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 561 is 1

Notice that 1 = HCF(561,1) .
