HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 768, 211, 546 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 768, 211, 546 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 768, 211, 546 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 768, 211, 546 is 1.

HCF(768, 211, 546) = 1

Highest common factor (HCF) of 768, 211, 546 is 1.

Highest Common Factor of 768,211,546 using Euclid's algorithm

Highest Common Factor of 768,211,546 is 1

Step 1: Since 768 > 211, we apply the division lemma to 768 and 211, to get

768 = 211 x 3 + 135

Step 2: Since the reminder 211 ≠ 0, we apply division lemma to 135 and 211, to get

211 = 135 x 1 + 76

Step 3: We consider the new divisor 135 and the new remainder 76, and apply the division lemma to get

135 = 76 x 1 + 59

We consider the new divisor 76 and the new remainder 59,and apply the division lemma to get

76 = 59 x 1 + 17

We consider the new divisor 59 and the new remainder 17,and apply the division lemma to get

59 = 17 x 3 + 8

We consider the new divisor 17 and the new remainder 8,and apply the division lemma to get

17 = 8 x 2 + 1

We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get

8 = 1 x 8 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 768 and 211 is 1

Notice that 1 = HCF(8,1) = HCF(17,8) = HCF(59,17) = HCF(76,59) = HCF(135,76) = HCF(211,135) = HCF(768,211) .

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

Step 1: Since 546 > 1, we apply the division lemma to 546 and 1, to get

546 = 1 x 546 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 546 is 1

Notice that 1 = HCF(546,1) .
