HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 681, 401, 545 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 681, 401, 545 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 681, 401, 545 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 681, 401, 545 is 1.

HCF(681, 401, 545) = 1

Highest common factor (HCF) of 681, 401, 545 is 1.

Highest Common Factor of 681,401,545 using Euclid's algorithm

Highest Common Factor of 681,401,545 is 1

Step 1: Since 681 > 401, we apply the division lemma to 681 and 401, to get

681 = 401 x 1 + 280

Step 2: Since the reminder 401 ≠ 0, we apply division lemma to 280 and 401, to get

401 = 280 x 1 + 121

Step 3: We consider the new divisor 280 and the new remainder 121, and apply the division lemma to get

280 = 121 x 2 + 38

We consider the new divisor 121 and the new remainder 38,and apply the division lemma to get

121 = 38 x 3 + 7

We consider the new divisor 38 and the new remainder 7,and apply the division lemma to get

38 = 7 x 5 + 3

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

7 = 3 x 2 + 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 681 and 401 is 1

Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(38,7) = HCF(121,38) = HCF(280,121) = HCF(401,280) = HCF(681,401) .

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

Step 1: Since 545 > 1, we apply the division lemma to 545 and 1, to get

545 = 1 x 545 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 545 is 1

Notice that 1 = HCF(545,1) .
