HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 439, 618, 71 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 439, 618, 71 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, 618, 71 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, 618, 71 is 1.

HCF(439, 618, 71) = 1

Highest common factor (HCF) of 439, 618, 71 is 1.

Highest Common Factor of 439,618,71 using Euclid's algorithm

Highest Common Factor of 439,618,71 is 1

Step 1: Since 618 > 439, we apply the division lemma to 618 and 439, to get

618 = 439 x 1 + 179

Step 2: Since the reminder 439 ≠ 0, we apply division lemma to 179 and 439, to get

439 = 179 x 2 + 81

Step 3: We consider the new divisor 179 and the new remainder 81, and apply the division lemma to get

179 = 81 x 2 + 17

We consider the new divisor 81 and the new remainder 17,and apply the division lemma to get

81 = 17 x 4 + 13

We consider the new divisor 17 and the new remainder 13,and apply the division lemma to get

17 = 13 x 1 + 4

We consider the new divisor 13 and the new remainder 4,and apply the division lemma to get

13 = 4 x 3 + 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 618 is 1

Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(17,13) = HCF(81,17) = HCF(179,81) = HCF(439,179) = HCF(618,439) .

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

Step 1: Since 71 > 1, we apply the division lemma to 71 and 1, to get

71 = 1 x 71 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 71 is 1

Notice that 1 = HCF(71,1) .
