HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 682, 481, 257 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 682, 481, 257 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 682, 481, 257 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 682, 481, 257 is 1.

HCF(682, 481, 257) = 1

Highest common factor (HCF) of 682, 481, 257 is 1.

Highest Common Factor of 682,481,257 using Euclid's algorithm

Highest Common Factor of 682,481,257 is 1

Step 1: Since 682 > 481, we apply the division lemma to 682 and 481, to get

682 = 481 x 1 + 201

Step 2: Since the reminder 481 ≠ 0, we apply division lemma to 201 and 481, to get

481 = 201 x 2 + 79

Step 3: We consider the new divisor 201 and the new remainder 79, and apply the division lemma to get

201 = 79 x 2 + 43

We consider the new divisor 79 and the new remainder 43,and apply the division lemma to get

79 = 43 x 1 + 36

We consider the new divisor 43 and the new remainder 36,and apply the division lemma to get

43 = 36 x 1 + 7

We consider the new divisor 36 and the new remainder 7,and apply the division lemma to get

36 = 7 x 5 + 1

We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get

7 = 1 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 682 and 481 is 1

Notice that 1 = HCF(7,1) = HCF(36,7) = HCF(43,36) = HCF(79,43) = HCF(201,79) = HCF(481,201) = HCF(682,481) .

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

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

257 = 1 x 257 + 0

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

Notice that 1 = HCF(257,1) .
