HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 697, 517, 826, 730 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 697, 517, 826, 730 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 697, 517, 826, 730 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 697, 517, 826, 730 is 1.

HCF(697, 517, 826, 730) = 1

Highest common factor (HCF) of 697, 517, 826, 730 is 1.

Highest Common Factor of 697,517,826,730 using Euclid's algorithm

Highest Common Factor of 697,517,826,730 is 1

Step 1: Since 697 > 517, we apply the division lemma to 697 and 517, to get

697 = 517 x 1 + 180

Step 2: Since the reminder 517 ≠ 0, we apply division lemma to 180 and 517, to get

517 = 180 x 2 + 157

Step 3: We consider the new divisor 180 and the new remainder 157, and apply the division lemma to get

180 = 157 x 1 + 23

We consider the new divisor 157 and the new remainder 23,and apply the division lemma to get

157 = 23 x 6 + 19

We consider the new divisor 23 and the new remainder 19,and apply the division lemma to get

23 = 19 x 1 + 4

We consider the new divisor 19 and the new remainder 4,and apply the division lemma to get

19 = 4 x 4 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 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 697 and 517 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(19,4) = HCF(23,19) = HCF(157,23) = HCF(180,157) = HCF(517,180) = HCF(697,517) .

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

Step 1: Since 826 > 1, we apply the division lemma to 826 and 1, to get

826 = 1 x 826 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 826 is 1

Notice that 1 = HCF(826,1) .

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

Step 1: Since 730 > 1, we apply the division lemma to 730 and 1, to get

730 = 1 x 730 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 730 is 1

Notice that 1 = HCF(730,1) .
