HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 543, 668, 767 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 543, 668, 767 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, 668, 767 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, 668, 767 is 1.

HCF(543, 668, 767) = 1

HCF of 543, 668, 767 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, 668, 767 is 1.

Highest Common Factor of 543,668,767 using Euclid's algorithm

Highest Common Factor of 543,668,767 is 1

Step 1: Since 668 > 543, we apply the division lemma to 668 and 543, to get

668 = 543 x 1 + 125

Step 2: Since the reminder 543 ≠ 0, we apply division lemma to 125 and 543, to get

543 = 125 x 4 + 43

Step 3: We consider the new divisor 125 and the new remainder 43, and apply the division lemma to get

125 = 43 x 2 + 39

We consider the new divisor 43 and the new remainder 39,and apply the division lemma to get

43 = 39 x 1 + 4

We consider the new divisor 39 and the new remainder 4,and apply the division lemma to get

39 = 4 x 9 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 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 668 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(39,4) = HCF(43,39) = HCF(125,43) = HCF(543,125) = HCF(668,543) .

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

Step 1: Since 767 > 1, we apply the division lemma to 767 and 1, to get

767 = 1 x 767 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 767 is 1

Notice that 1 = HCF(767,1) .
