HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 917, 681 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 917, 681 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 917, 681 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 917, 681 is 1.

HCF(917, 681) = 1

Highest common factor (HCF) of 917, 681 is 1.

Highest Common Factor of 917,681 using Euclid's algorithm

Highest Common Factor of 917,681 is 1

Step 1: Since 917 > 681, we apply the division lemma to 917 and 681, to get

917 = 681 x 1 + 236

Step 2: Since the reminder 681 ≠ 0, we apply division lemma to 236 and 681, to get

681 = 236 x 2 + 209

Step 3: We consider the new divisor 236 and the new remainder 209, and apply the division lemma to get

236 = 209 x 1 + 27

We consider the new divisor 209 and the new remainder 27,and apply the division lemma to get

209 = 27 x 7 + 20

We consider the new divisor 27 and the new remainder 20,and apply the division lemma to get

27 = 20 x 1 + 7

We consider the new divisor 20 and the new remainder 7,and apply the division lemma to get

20 = 7 x 2 + 6

We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get

7 = 6 x 1 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 917 and 681 is 1

Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(20,7) = HCF(27,20) = HCF(209,27) = HCF(236,209) = HCF(681,236) = HCF(917,681) .
