HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 681, 436, 533 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 681, 436, 533 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 681, 436, 533 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 681, 436, 533 is 1.

HCF(681, 436, 533) = 1

HCF of 681, 436, 533 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 681, 436, 533 is 1.

Highest Common Factor of 681,436,533 using Euclid's algorithm

Highest Common Factor of 681,436,533 is 1

Step 1: Since 681 > 436, we apply the division lemma to 681 and 436, to get

681 = 436 x 1 + 245

Step 2: Since the reminder 436 ≠ 0, we apply division lemma to 245 and 436, to get

436 = 245 x 1 + 191

Step 3: We consider the new divisor 245 and the new remainder 191, and apply the division lemma to get

245 = 191 x 1 + 54

We consider the new divisor 191 and the new remainder 54,and apply the division lemma to get

191 = 54 x 3 + 29

We consider the new divisor 54 and the new remainder 29,and apply the division lemma to get

54 = 29 x 1 + 25

We consider the new divisor 29 and the new remainder 25,and apply the division lemma to get

29 = 25 x 1 + 4

We consider the new divisor 25 and the new remainder 4,and apply the division lemma to get

25 = 4 x 6 + 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 681 and 436 is 1

Notice that 1 = HCF(4,1) = HCF(25,4) = HCF(29,25) = HCF(54,29) = HCF(191,54) = HCF(245,191) = HCF(436,245) = HCF(681,436) .

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

Step 1: Since 533 > 1, we apply the division lemma to 533 and 1, to get

533 = 1 x 533 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 533 is 1

Notice that 1 = HCF(533,1) .
