HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 439, 557, 431 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 439, 557, 431 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, 557, 431 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, 557, 431 is 1.

HCF(439, 557, 431) = 1

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

HCF of:

Highest common factor (HCF) of 439, 557, 431 is 1.

Highest Common Factor of 439,557,431 using Euclid's algorithm

Highest Common Factor of 439,557,431 is 1

Step 1: Since 557 > 439, we apply the division lemma to 557 and 439, to get

557 = 439 x 1 + 118

Step 2: Since the reminder 439 ≠ 0, we apply division lemma to 118 and 439, to get

439 = 118 x 3 + 85

Step 3: We consider the new divisor 118 and the new remainder 85, and apply the division lemma to get

118 = 85 x 1 + 33

We consider the new divisor 85 and the new remainder 33,and apply the division lemma to get

85 = 33 x 2 + 19

We consider the new divisor 33 and the new remainder 19,and apply the division lemma to get

33 = 19 x 1 + 14

We consider the new divisor 19 and the new remainder 14,and apply the division lemma to get

19 = 14 x 1 + 5

We consider the new divisor 14 and the new remainder 5,and apply the division lemma to get

14 = 5 x 2 + 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 439 and 557 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(19,14) = HCF(33,19) = HCF(85,33) = HCF(118,85) = HCF(439,118) = HCF(557,439) .

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

Step 1: Since 431 > 1, we apply the division lemma to 431 and 1, to get

431 = 1 x 431 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 431 is 1

Notice that 1 = HCF(431,1) .
