HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 459, 7257, 7471 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 459, 7257, 7471 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 459, 7257, 7471 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 459, 7257, 7471 is 1.

HCF(459, 7257, 7471) = 1

Highest common factor (HCF) of 459, 7257, 7471 is 1.

Highest Common Factor of 459,7257,7471 using Euclid's algorithm

Highest Common Factor of 459,7257,7471 is 1

Step 1: Since 7257 > 459, we apply the division lemma to 7257 and 459, to get

7257 = 459 x 15 + 372

Step 2: Since the reminder 459 ≠ 0, we apply division lemma to 372 and 459, to get

459 = 372 x 1 + 87

Step 3: We consider the new divisor 372 and the new remainder 87, and apply the division lemma to get

372 = 87 x 4 + 24

We consider the new divisor 87 and the new remainder 24,and apply the division lemma to get

87 = 24 x 3 + 15

We consider the new divisor 24 and the new remainder 15,and apply the division lemma to get

24 = 15 x 1 + 9

We consider the new divisor 15 and the new remainder 9,and apply the division lemma to get

15 = 9 x 1 + 6

We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get

9 = 6 x 1 + 3

We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 459 and 7257 is 3

Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(24,15) = HCF(87,24) = HCF(372,87) = HCF(459,372) = HCF(7257,459) .

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

Step 1: Since 7471 > 3, we apply the division lemma to 7471 and 3, to get

7471 = 3 x 2490 + 1

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 7471 is 1

Notice that 1 = HCF(3,1) = HCF(7471,3) .
