HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 517, 769, 647, 516 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 517, 769, 647, 516 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, 769, 647, 516 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, 769, 647, 516 is 1.

HCF(517, 769, 647, 516) = 1

Highest Common Factor of 517,769,647,516 using Euclid's algorithm

Highest Common Factor of 517,769,647,516 is 1

Step 1: Since 769 > 517, we apply the division lemma to 769 and 517, to get

769 = 517 x 1 + 252

Step 2: Since the reminder 517 ≠ 0, we apply division lemma to 252 and 517, to get

517 = 252 x 2 + 13

Step 3: We consider the new divisor 252 and the new remainder 13, and apply the division lemma to get

252 = 13 x 19 + 5

We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get

13 = 5 x 2 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 769 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(252,13) = HCF(517,252) = HCF(769,517) .

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

Step 1: Since 647 > 1, we apply the division lemma to 647 and 1, to get

647 = 1 x 647 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 647 is 1

Notice that 1 = HCF(647,1) .

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

Step 1: Since 516 > 1, we apply the division lemma to 516 and 1, to get

516 = 1 x 516 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 516 is 1

Notice that 1 = HCF(516,1) .
