HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 480, 817, 679 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 480, 817, 679 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 480, 817, 679 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 480, 817, 679 is 1.

HCF(480, 817, 679) = 1

Highest common factor (HCF) of 480, 817, 679 is 1.

Highest Common Factor of 480,817,679 using Euclid's algorithm

Highest Common Factor of 480,817,679 is 1

Step 1: Since 817 > 480, we apply the division lemma to 817 and 480, to get

817 = 480 x 1 + 337

Step 2: Since the reminder 480 ≠ 0, we apply division lemma to 337 and 480, to get

480 = 337 x 1 + 143

Step 3: We consider the new divisor 337 and the new remainder 143, and apply the division lemma to get

337 = 143 x 2 + 51

We consider the new divisor 143 and the new remainder 51,and apply the division lemma to get

143 = 51 x 2 + 41

We consider the new divisor 51 and the new remainder 41,and apply the division lemma to get

51 = 41 x 1 + 10

We consider the new divisor 41 and the new remainder 10,and apply the division lemma to get

41 = 10 x 4 + 1

We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get

10 = 1 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 480 and 817 is 1

Notice that 1 = HCF(10,1) = HCF(41,10) = HCF(51,41) = HCF(143,51) = HCF(337,143) = HCF(480,337) = HCF(817,480) .

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

Step 1: Since 679 > 1, we apply the division lemma to 679 and 1, to get

679 = 1 x 679 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 679 is 1

Notice that 1 = HCF(679,1) .
