HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 401, 549, 678 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 401, 549, 678 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 401, 549, 678 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 401, 549, 678 is 1.

HCF(401, 549, 678) = 1

HCF of 401, 549, 678 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 401, 549, 678 is 1.

Highest Common Factor of 401,549,678 using Euclid's algorithm

Highest Common Factor of 401,549,678 is 1

Step 1: Since 549 > 401, we apply the division lemma to 549 and 401, to get

549 = 401 x 1 + 148

Step 2: Since the reminder 401 ≠ 0, we apply division lemma to 148 and 401, to get

401 = 148 x 2 + 105

Step 3: We consider the new divisor 148 and the new remainder 105, and apply the division lemma to get

148 = 105 x 1 + 43

We consider the new divisor 105 and the new remainder 43,and apply the division lemma to get

105 = 43 x 2 + 19

We consider the new divisor 43 and the new remainder 19,and apply the division lemma to get

43 = 19 x 2 + 5

We consider the new divisor 19 and the new remainder 5,and apply the division lemma to get

19 = 5 x 3 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 401 and 549 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(19,5) = HCF(43,19) = HCF(105,43) = HCF(148,105) = HCF(401,148) = HCF(549,401) .

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

Step 1: Since 678 > 1, we apply the division lemma to 678 and 1, to get

678 = 1 x 678 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 678 is 1

Notice that 1 = HCF(678,1) .
