HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 517, 439, 676, 727 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 517, 439, 676, 727 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 517, 439, 676, 727 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 517, 439, 676, 727 is 1.

HCF(517, 439, 676, 727) = 1

Highest Common Factor of 517,439,676,727 using Euclid's algorithm

Highest Common Factor of 517,439,676,727 is 1

Step 1: Since 517 > 439, we apply the division lemma to 517 and 439, to get

517 = 439 x 1 + 78

Step 2: Since the reminder 439 ≠ 0, we apply division lemma to 78 and 439, to get

439 = 78 x 5 + 49

Step 3: We consider the new divisor 78 and the new remainder 49, and apply the division lemma to get

78 = 49 x 1 + 29

We consider the new divisor 49 and the new remainder 29,and apply the division lemma to get

49 = 29 x 1 + 20

We consider the new divisor 29 and the new remainder 20,and apply the division lemma to get

29 = 20 x 1 + 9

We consider the new divisor 20 and the new remainder 9,and apply the division lemma to get

20 = 9 x 2 + 2

We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get

9 = 2 x 4 + 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 517 and 439 is 1

Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(20,9) = HCF(29,20) = HCF(49,29) = HCF(78,49) = HCF(439,78) = HCF(517,439) .

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

Step 1: Since 676 > 1, we apply the division lemma to 676 and 1, to get

676 = 1 x 676 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 676 is 1

Notice that 1 = HCF(676,1) .

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

Step 1: Since 727 > 1, we apply the division lemma to 727 and 1, to get

727 = 1 x 727 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 727 is 1

Notice that 1 = HCF(727,1) .
