HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 257, 757, 611 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 257, 757, 611 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 257, 757, 611 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 257, 757, 611 is 1.

HCF(257, 757, 611) = 1

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

HCF of:

Highest common factor (HCF) of 257, 757, 611 is 1.

Highest Common Factor of 257,757,611 using Euclid's algorithm

Highest Common Factor of 257,757,611 is 1

Step 1: Since 757 > 257, we apply the division lemma to 757 and 257, to get

757 = 257 x 2 + 243

Step 2: Since the reminder 257 ≠ 0, we apply division lemma to 243 and 257, to get

257 = 243 x 1 + 14

Step 3: We consider the new divisor 243 and the new remainder 14, and apply the division lemma to get

243 = 14 x 17 + 5

We consider the new divisor 14 and the new remainder 5,and apply the division lemma to get

14 = 5 x 2 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 257 and 757 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(243,14) = HCF(257,243) = HCF(757,257) .

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

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

611 = 1 x 611 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 611 is 1

Notice that 1 = HCF(611,1) .
