HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 454, 765, 533 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 454, 765, 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 454, 765, 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 454, 765, 533 is 1.

HCF(454, 765, 533) = 1

HCF of 454, 765, 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 454, 765, 533 is 1.

Highest Common Factor of 454,765,533 using Euclid's algorithm

Highest Common Factor of 454,765,533 is 1

Step 1: Since 765 > 454, we apply the division lemma to 765 and 454, to get

765 = 454 x 1 + 311

Step 2: Since the reminder 454 ≠ 0, we apply division lemma to 311 and 454, to get

454 = 311 x 1 + 143

Step 3: We consider the new divisor 311 and the new remainder 143, and apply the division lemma to get

311 = 143 x 2 + 25

We consider the new divisor 143 and the new remainder 25,and apply the division lemma to get

143 = 25 x 5 + 18

We consider the new divisor 25 and the new remainder 18,and apply the division lemma to get

25 = 18 x 1 + 7

We consider the new divisor 18 and the new remainder 7,and apply the division lemma to get

18 = 7 x 2 + 4

We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get

7 = 4 x 1 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 454 and 765 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(18,7) = HCF(25,18) = HCF(143,25) = HCF(311,143) = HCF(454,311) = HCF(765,454) .

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) .
