HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 726, 369, 671 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 726, 369, 671 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 726, 369, 671 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 726, 369, 671 is 1.

HCF(726, 369, 671) = 1

HCF of 726, 369, 671 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 726, 369, 671 is 1.

Highest Common Factor of 726,369,671 using Euclid's algorithm

Highest Common Factor of 726,369,671 is 1

Step 1: Since 726 > 369, we apply the division lemma to 726 and 369, to get

726 = 369 x 1 + 357

Step 2: Since the reminder 369 ≠ 0, we apply division lemma to 357 and 369, to get

369 = 357 x 1 + 12

Step 3: We consider the new divisor 357 and the new remainder 12, and apply the division lemma to get

357 = 12 x 29 + 9

We consider the new divisor 12 and the new remainder 9,and apply the division lemma to get

12 = 9 x 1 + 3

We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get

9 = 3 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 726 and 369 is 3

Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(357,12) = HCF(369,357) = HCF(726,369) .

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

Step 1: Since 671 > 3, we apply the division lemma to 671 and 3, to get

671 = 3 x 223 + 2

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

3 = 2 x 1 + 1

Step 3: 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 3 and 671 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(671,3) .
