HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 727, 687, 693 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 727, 687, 693 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 727, 687, 693 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 727, 687, 693 is 1.

HCF(727, 687, 693) = 1

Highest common factor (HCF) of 727, 687, 693 is 1.

Highest Common Factor of 727,687,693 using Euclid's algorithm

Highest Common Factor of 727,687,693 is 1

Step 1: Since 727 > 687, we apply the division lemma to 727 and 687, to get

727 = 687 x 1 + 40

Step 2: Since the reminder 687 ≠ 0, we apply division lemma to 40 and 687, to get

687 = 40 x 17 + 7

Step 3: We consider the new divisor 40 and the new remainder 7, and apply the division lemma to get

40 = 7 x 5 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 727 and 687 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(40,7) = HCF(687,40) = HCF(727,687) .

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

Step 1: Since 693 > 1, we apply the division lemma to 693 and 1, to get

693 = 1 x 693 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 693 is 1

Notice that 1 = HCF(693,1) .
