HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 478, 609, 726 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 478, 609, 726 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 478, 609, 726 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 478, 609, 726 is 1.

HCF(478, 609, 726) = 1

HCF of 478, 609, 726 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 478, 609, 726 is 1.

Highest Common Factor of 478,609,726 using Euclid's algorithm

Highest Common Factor of 478,609,726 is 1

Step 1: Since 609 > 478, we apply the division lemma to 609 and 478, to get

609 = 478 x 1 + 131

Step 2: Since the reminder 478 ≠ 0, we apply division lemma to 131 and 478, to get

478 = 131 x 3 + 85

Step 3: We consider the new divisor 131 and the new remainder 85, and apply the division lemma to get

131 = 85 x 1 + 46

We consider the new divisor 85 and the new remainder 46,and apply the division lemma to get

85 = 46 x 1 + 39

We consider the new divisor 46 and the new remainder 39,and apply the division lemma to get

46 = 39 x 1 + 7

We consider the new divisor 39 and the new remainder 7,and apply the division lemma to get

39 = 7 x 5 + 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 478 and 609 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(39,7) = HCF(46,39) = HCF(85,46) = HCF(131,85) = HCF(478,131) = HCF(609,478) .


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

Step 1: Since 726 > 1, we apply the division lemma to 726 and 1, to get

726 = 1 x 726 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 726 is 1

Notice that 1 = HCF(726,1) .
