HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 659, 479, 717 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 659, 479, 717 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 659, 479, 717 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 659, 479, 717 is 1.

HCF(659, 479, 717) = 1

HCF of 659, 479, 717 using Euclid's algorithm

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

Highest common factor (HCF) of 659, 479, 717 is 1.

Highest Common Factor of 659,479,717 using Euclid's algorithm

Highest Common Factor of 659,479,717 is 1

Step 1: Since 659 > 479, we apply the division lemma to 659 and 479, to get

659 = 479 x 1 + 180

Step 2: Since the reminder 479 ≠ 0, we apply division lemma to 180 and 479, to get

479 = 180 x 2 + 119

Step 3: We consider the new divisor 180 and the new remainder 119, and apply the division lemma to get

180 = 119 x 1 + 61

We consider the new divisor 119 and the new remainder 61,and apply the division lemma to get

119 = 61 x 1 + 58

We consider the new divisor 61 and the new remainder 58,and apply the division lemma to get

61 = 58 x 1 + 3

We consider the new divisor 58 and the new remainder 3,and apply the division lemma to get

58 = 3 x 19 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 659 and 479 is 1

Notice that 1 = HCF(3,1) = HCF(58,3) = HCF(61,58) = HCF(119,61) = HCF(180,119) = HCF(479,180) = HCF(659,479) .

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

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

717 = 1 x 717 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 717 is 1

Notice that 1 = HCF(717,1) .
