HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 717, 516, 779 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 717, 516, 779 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 717, 516, 779 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 717, 516, 779 is 1.

HCF(717, 516, 779) = 1

Highest common factor (HCF) of 717, 516, 779 is 1.

Highest Common Factor of 717,516,779 using Euclid's algorithm

Highest Common Factor of 717,516,779 is 1

Step 1: Since 717 > 516, we apply the division lemma to 717 and 516, to get

717 = 516 x 1 + 201

Step 2: Since the reminder 516 ≠ 0, we apply division lemma to 201 and 516, to get

516 = 201 x 2 + 114

Step 3: We consider the new divisor 201 and the new remainder 114, and apply the division lemma to get

201 = 114 x 1 + 87

We consider the new divisor 114 and the new remainder 87,and apply the division lemma to get

114 = 87 x 1 + 27

We consider the new divisor 87 and the new remainder 27,and apply the division lemma to get

87 = 27 x 3 + 6

We consider the new divisor 27 and the new remainder 6,and apply the division lemma to get

27 = 6 x 4 + 3

We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 717 and 516 is 3

Notice that 3 = HCF(6,3) = HCF(27,6) = HCF(87,27) = HCF(114,87) = HCF(201,114) = HCF(516,201) = HCF(717,516) .

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

Step 1: Since 779 > 3, we apply the division lemma to 779 and 3, to get

779 = 3 x 259 + 2

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get

3 = 2 x 1 + 1

Step 3: 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 3 and 779 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(779,3) .
