HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 611, 455, 211 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 611, 455, 211 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 611, 455, 211 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 611, 455, 211 is 1.

HCF(611, 455, 211) = 1

HCF of 611, 455, 211 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 611, 455, 211 is 1.

Highest Common Factor of 611,455,211 using Euclid's algorithm

Highest Common Factor of 611,455,211 is 1

Step 1: Since 611 > 455, we apply the division lemma to 611 and 455, to get

611 = 455 x 1 + 156

Step 2: Since the reminder 455 ≠ 0, we apply division lemma to 156 and 455, to get

455 = 156 x 2 + 143

Step 3: We consider the new divisor 156 and the new remainder 143, and apply the division lemma to get

156 = 143 x 1 + 13

We consider the new divisor 143 and the new remainder 13, and apply the division lemma to get

143 = 13 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 611 and 455 is 13

Notice that 13 = HCF(143,13) = HCF(156,143) = HCF(455,156) = HCF(611,455) .

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

Step 1: Since 211 > 13, we apply the division lemma to 211 and 13, to get

211 = 13 x 16 + 3

Step 2: Since the reminder 13 ≠ 0, we apply division lemma to 3 and 13, to get

13 = 3 x 4 + 1

Step 3: 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 13 and 211 is 1

Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(211,13) .
