HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 649, 727, 703 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 649, 727, 703 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 649, 727, 703 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 649, 727, 703 is 1.

HCF(649, 727, 703) = 1

HCF of 649, 727, 703 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 649, 727, 703 is 1.

Highest Common Factor of 649,727,703 using Euclid's algorithm

Highest Common Factor of 649,727,703 is 1

Step 1: Since 727 > 649, we apply the division lemma to 727 and 649, to get

727 = 649 x 1 + 78

Step 2: Since the reminder 649 ≠ 0, we apply division lemma to 78 and 649, to get

649 = 78 x 8 + 25

Step 3: We consider the new divisor 78 and the new remainder 25, and apply the division lemma to get

78 = 25 x 3 + 3

We consider the new divisor 25 and the new remainder 3,and apply the division lemma to get

25 = 3 x 8 + 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 649 and 727 is 1

Notice that 1 = HCF(3,1) = HCF(25,3) = HCF(78,25) = HCF(649,78) = HCF(727,649) .

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

Step 1: Since 703 > 1, we apply the division lemma to 703 and 1, to get

703 = 1 x 703 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 703 is 1

Notice that 1 = HCF(703,1) .
