HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 543, 332, 861 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 543, 332, 861 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, 332, 861 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, 332, 861 is 1.

HCF(543, 332, 861) = 1

HCF of 543, 332, 861 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, 332, 861 is 1.

Highest Common Factor of 543,332,861 using Euclid's algorithm

Highest Common Factor of 543,332,861 is 1

Step 1: Since 543 > 332, we apply the division lemma to 543 and 332, to get

543 = 332 x 1 + 211

Step 2: Since the reminder 332 ≠ 0, we apply division lemma to 211 and 332, to get

332 = 211 x 1 + 121

Step 3: We consider the new divisor 211 and the new remainder 121, and apply the division lemma to get

211 = 121 x 1 + 90

We consider the new divisor 121 and the new remainder 90,and apply the division lemma to get

121 = 90 x 1 + 31

We consider the new divisor 90 and the new remainder 31,and apply the division lemma to get

90 = 31 x 2 + 28

We consider the new divisor 31 and the new remainder 28,and apply the division lemma to get

31 = 28 x 1 + 3

We consider the new divisor 28 and the new remainder 3,and apply the division lemma to get

28 = 3 x 9 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma 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 543 and 332 is 1

Notice that 1 = HCF(3,1) = HCF(28,3) = HCF(31,28) = HCF(90,31) = HCF(121,90) = HCF(211,121) = HCF(332,211) = HCF(543,332) .

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

Step 1: Since 861 > 1, we apply the division lemma to 861 and 1, to get

861 = 1 x 861 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 861 is 1

Notice that 1 = HCF(861,1) .
