HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 450, 571, 826 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 450, 571, 826 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 450, 571, 826 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 450, 571, 826 is 1.

HCF(450, 571, 826) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 450, 571, 826 is 1.

Highest Common Factor of 450,571,826 using Euclid's algorithm

Highest Common Factor of 450,571,826 is 1

Step 1: Since 571 > 450, we apply the division lemma to 571 and 450, to get

571 = 450 x 1 + 121

Step 2: Since the reminder 450 ≠ 0, we apply division lemma to 121 and 450, to get

450 = 121 x 3 + 87

Step 3: We consider the new divisor 121 and the new remainder 87, and apply the division lemma to get

121 = 87 x 1 + 34

We consider the new divisor 87 and the new remainder 34,and apply the division lemma to get

87 = 34 x 2 + 19

We consider the new divisor 34 and the new remainder 19,and apply the division lemma to get

34 = 19 x 1 + 15

We consider the new divisor 19 and the new remainder 15,and apply the division lemma to get

19 = 15 x 1 + 4

We consider the new divisor 15 and the new remainder 4,and apply the division lemma to get

15 = 4 x 3 + 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 450 and 571 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(15,4) = HCF(19,15) = HCF(34,19) = HCF(87,34) = HCF(121,87) = HCF(450,121) = HCF(571,450) .

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

Step 1: Since 826 > 1, we apply the division lemma to 826 and 1, to get

826 = 1 x 826 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 826 is 1

Notice that 1 = HCF(826,1) .
