HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 549, 931, 387 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 549, 931, 387 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 549, 931, 387 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 549, 931, 387 is 1.

HCF(549, 931, 387) = 1

HCF of 549, 931, 387 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

Highest common factor (HCF) of 549, 931, 387 is 1.

Highest Common Factor of 549,931,387 using Euclid's algorithm

Highest Common Factor of 549,931,387 is 1

Step 1: Since 931 > 549, we apply the division lemma to 931 and 549, to get

931 = 549 x 1 + 382

Step 2: Since the reminder 549 ≠ 0, we apply division lemma to 382 and 549, to get

549 = 382 x 1 + 167

Step 3: We consider the new divisor 382 and the new remainder 167, and apply the division lemma to get

382 = 167 x 2 + 48

We consider the new divisor 167 and the new remainder 48,and apply the division lemma to get

167 = 48 x 3 + 23

We consider the new divisor 48 and the new remainder 23,and apply the division lemma to get

48 = 23 x 2 + 2

We consider the new divisor 23 and the new remainder 2,and apply the division lemma to get

23 = 2 x 11 + 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 549 and 931 is 1

Notice that 1 = HCF(2,1) = HCF(23,2) = HCF(48,23) = HCF(167,48) = HCF(382,167) = HCF(549,382) = HCF(931,549) .

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

Step 1: Since 387 > 1, we apply the division lemma to 387 and 1, to get

387 = 1 x 387 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 387 is 1

Notice that 1 = HCF(387,1) .
