HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 676, 485, 268 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 676, 485, 268 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 676, 485, 268 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 676, 485, 268 is 1.

HCF(676, 485, 268) = 1

HCF of 676, 485, 268 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 676, 485, 268 is 1.

Highest Common Factor of 676,485,268 using Euclid's algorithm

Highest Common Factor of 676,485,268 is 1

Step 1: Since 676 > 485, we apply the division lemma to 676 and 485, to get

676 = 485 x 1 + 191

Step 2: Since the reminder 485 ≠ 0, we apply division lemma to 191 and 485, to get

485 = 191 x 2 + 103

Step 3: We consider the new divisor 191 and the new remainder 103, and apply the division lemma to get

191 = 103 x 1 + 88

We consider the new divisor 103 and the new remainder 88,and apply the division lemma to get

103 = 88 x 1 + 15

We consider the new divisor 88 and the new remainder 15,and apply the division lemma to get

88 = 15 x 5 + 13

We consider the new divisor 15 and the new remainder 13,and apply the division lemma to get

15 = 13 x 1 + 2

We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get

13 = 2 x 6 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 676 and 485 is 1

Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(15,13) = HCF(88,15) = HCF(103,88) = HCF(191,103) = HCF(485,191) = HCF(676,485) .

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

Step 1: Since 268 > 1, we apply the division lemma to 268 and 1, to get

268 = 1 x 268 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 268 is 1

Notice that 1 = HCF(268,1) .
