HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 717, 328, 508 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 717, 328, 508 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, 328, 508 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, 328, 508 is 1.

HCF(717, 328, 508) = 1

Highest common factor (HCF) of 717, 328, 508 is 1.

Highest Common Factor of 717,328,508 using Euclid's algorithm

Highest Common Factor of 717,328,508 is 1

Step 1: Since 717 > 328, we apply the division lemma to 717 and 328, to get

717 = 328 x 2 + 61

Step 2: Since the reminder 328 ≠ 0, we apply division lemma to 61 and 328, to get

328 = 61 x 5 + 23

Step 3: We consider the new divisor 61 and the new remainder 23, and apply the division lemma to get

61 = 23 x 2 + 15

We consider the new divisor 23 and the new remainder 15,and apply the division lemma to get

23 = 15 x 1 + 8

We consider the new divisor 15 and the new remainder 8,and apply the division lemma to get

15 = 8 x 1 + 7

We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get

8 = 7 x 1 + 1

We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get

7 = 1 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 717 and 328 is 1

Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(15,8) = HCF(23,15) = HCF(61,23) = HCF(328,61) = HCF(717,328) .

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

Step 1: Since 508 > 1, we apply the division lemma to 508 and 1, to get

508 = 1 x 508 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 508 is 1

Notice that 1 = HCF(508,1) .
