HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 242, 433, 682 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 242, 433, 682 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 242, 433, 682 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 242, 433, 682 is 1.

HCF(242, 433, 682) = 1

Highest common factor (HCF) of 242, 433, 682 is 1.

Highest Common Factor of 242,433,682 using Euclid's algorithm

Highest Common Factor of 242,433,682 is 1

Step 1: Since 433 > 242, we apply the division lemma to 433 and 242, to get

433 = 242 x 1 + 191

Step 2: Since the reminder 242 ≠ 0, we apply division lemma to 191 and 242, to get

242 = 191 x 1 + 51

Step 3: We consider the new divisor 191 and the new remainder 51, and apply the division lemma to get

191 = 51 x 3 + 38

We consider the new divisor 51 and the new remainder 38,and apply the division lemma to get

51 = 38 x 1 + 13

We consider the new divisor 38 and the new remainder 13,and apply the division lemma to get

38 = 13 x 2 + 12

We consider the new divisor 13 and the new remainder 12,and apply the division lemma to get

13 = 12 x 1 + 1

We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get

12 = 1 x 12 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 242 and 433 is 1

Notice that 1 = HCF(12,1) = HCF(13,12) = HCF(38,13) = HCF(51,38) = HCF(191,51) = HCF(242,191) = HCF(433,242) .

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

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

682 = 1 x 682 + 0

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

Notice that 1 = HCF(682,1) .
