HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 730, 451, 471 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 730, 451, 471 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 730, 451, 471 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 730, 451, 471 is 1.

HCF(730, 451, 471) = 1

Highest Common Factor of 730,451,471 using Euclid's algorithm

Highest Common Factor of 730,451,471 is 1

Step 1: Since 730 > 451, we apply the division lemma to 730 and 451, to get

730 = 451 x 1 + 279

Step 2: Since the reminder 451 ≠ 0, we apply division lemma to 279 and 451, to get

451 = 279 x 1 + 172

Step 3: We consider the new divisor 279 and the new remainder 172, and apply the division lemma to get

279 = 172 x 1 + 107

We consider the new divisor 172 and the new remainder 107,and apply the division lemma to get

172 = 107 x 1 + 65

We consider the new divisor 107 and the new remainder 65,and apply the division lemma to get

107 = 65 x 1 + 42

We consider the new divisor 65 and the new remainder 42,and apply the division lemma to get

65 = 42 x 1 + 23

We consider the new divisor 42 and the new remainder 23,and apply the division lemma to get

42 = 23 x 1 + 19

We consider the new divisor 23 and the new remainder 19,and apply the division lemma to get

23 = 19 x 1 + 4

We consider the new divisor 19 and the new remainder 4,and apply the division lemma to get

19 = 4 x 4 + 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 730 and 451 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(19,4) = HCF(23,19) = HCF(42,23) = HCF(65,42) = HCF(107,65) = HCF(172,107) = HCF(279,172) = HCF(451,279) = HCF(730,451) .


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

Step 1: Since 471 > 1, we apply the division lemma to 471 and 1, to get

471 = 1 x 471 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 471 is 1

Notice that 1 = HCF(471,1) .
