HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 734, 647, 609 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 734, 647, 609 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 734, 647, 609 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 734, 647, 609 is 1.

HCF(734, 647, 609) = 1

HCF of 734, 647, 609 using Euclid's algorithm

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

Highest common factor (HCF) of 734, 647, 609 is 1.

Highest Common Factor of 734,647,609 using Euclid's algorithm

Highest Common Factor of 734,647,609 is 1

Step 1: Since 734 > 647, we apply the division lemma to 734 and 647, to get

734 = 647 x 1 + 87

Step 2: Since the reminder 647 ≠ 0, we apply division lemma to 87 and 647, to get

647 = 87 x 7 + 38

Step 3: We consider the new divisor 87 and the new remainder 38, and apply the division lemma to get

87 = 38 x 2 + 11

We consider the new divisor 38 and the new remainder 11,and apply the division lemma to get

38 = 11 x 3 + 5

We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get

11 = 5 x 2 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 734 and 647 is 1

Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(38,11) = HCF(87,38) = HCF(647,87) = HCF(734,647) .

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

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

609 = 1 x 609 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 609 is 1

Notice that 1 = HCF(609,1) .
