HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 717, 7097 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 717, 7097 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, 7097 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, 7097 is 1.

HCF(717, 7097) = 1

Highest common factor (HCF) of 717, 7097 is 1.

Highest Common Factor of 717,7097 using Euclid's algorithm

Highest Common Factor of 717,7097 is 1

Step 1: Since 7097 > 717, we apply the division lemma to 7097 and 717, to get

7097 = 717 x 9 + 644

Step 2: Since the reminder 717 ≠ 0, we apply division lemma to 644 and 717, to get

717 = 644 x 1 + 73

Step 3: We consider the new divisor 644 and the new remainder 73, and apply the division lemma to get

644 = 73 x 8 + 60

We consider the new divisor 73 and the new remainder 60,and apply the division lemma to get

73 = 60 x 1 + 13

We consider the new divisor 60 and the new remainder 13,and apply the division lemma to get

60 = 13 x 4 + 8

We consider the new divisor 13 and the new remainder 8,and apply the division lemma to get

13 = 8 x 1 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

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 717 and 7097 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(60,13) = HCF(73,60) = HCF(644,73) = HCF(717,644) = HCF(7097,717) .
