HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 439, 857, 487 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 439, 857, 487 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 439, 857, 487 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 439, 857, 487 is 1.

HCF(439, 857, 487) = 1

HCF of 439, 857, 487 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 439, 857, 487 is 1.

Highest Common Factor of 439,857,487 using Euclid's algorithm

Highest Common Factor of 439,857,487 is 1

Step 1: Since 857 > 439, we apply the division lemma to 857 and 439, to get

857 = 439 x 1 + 418

Step 2: Since the reminder 439 ≠ 0, we apply division lemma to 418 and 439, to get

439 = 418 x 1 + 21

Step 3: We consider the new divisor 418 and the new remainder 21, and apply the division lemma to get

418 = 21 x 19 + 19

We consider the new divisor 21 and the new remainder 19,and apply the division lemma to get

21 = 19 x 1 + 2

We consider the new divisor 19 and the new remainder 2,and apply the division lemma to get

19 = 2 x 9 + 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 439 and 857 is 1

Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(21,19) = HCF(418,21) = HCF(439,418) = HCF(857,439) .

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

Step 1: Since 487 > 1, we apply the division lemma to 487 and 1, to get

487 = 1 x 487 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 487 is 1

Notice that 1 = HCF(487,1) .
