HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 644, 347, 718 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 644, 347, 718 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 644, 347, 718 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 644, 347, 718 is 1.

HCF(644, 347, 718) = 1

HCF of 644, 347, 718 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 644, 347, 718 is 1.

Highest Common Factor of 644,347,718 using Euclid's algorithm

Highest Common Factor of 644,347,718 is 1

Step 1: Since 644 > 347, we apply the division lemma to 644 and 347, to get

644 = 347 x 1 + 297

Step 2: Since the reminder 347 ≠ 0, we apply division lemma to 297 and 347, to get

347 = 297 x 1 + 50

Step 3: We consider the new divisor 297 and the new remainder 50, and apply the division lemma to get

297 = 50 x 5 + 47

We consider the new divisor 50 and the new remainder 47,and apply the division lemma to get

50 = 47 x 1 + 3

We consider the new divisor 47 and the new remainder 3,and apply the division lemma to get

47 = 3 x 15 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 644 and 347 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(47,3) = HCF(50,47) = HCF(297,50) = HCF(347,297) = HCF(644,347) .

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

Step 1: Since 718 > 1, we apply the division lemma to 718 and 1, to get

718 = 1 x 718 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 718 is 1

Notice that 1 = HCF(718,1) .
