HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 718, 8991 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 718, 8991 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 718, 8991 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 718, 8991 is 1.

HCF(718, 8991) = 1

Highest common factor (HCF) of 718, 8991 is 1.

Highest Common Factor of 718,8991 using Euclid's algorithm

Highest Common Factor of 718,8991 is 1

Step 1: Since 8991 > 718, we apply the division lemma to 8991 and 718, to get

8991 = 718 x 12 + 375

Step 2: Since the reminder 718 ≠ 0, we apply division lemma to 375 and 718, to get

718 = 375 x 1 + 343

Step 3: We consider the new divisor 375 and the new remainder 343, and apply the division lemma to get

375 = 343 x 1 + 32

We consider the new divisor 343 and the new remainder 32,and apply the division lemma to get

343 = 32 x 10 + 23

We consider the new divisor 32 and the new remainder 23,and apply the division lemma to get

32 = 23 x 1 + 9

We consider the new divisor 23 and the new remainder 9,and apply the division lemma to get

23 = 9 x 2 + 5

We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get

9 = 5 x 1 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 718 and 8991 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(23,9) = HCF(32,23) = HCF(343,32) = HCF(375,343) = HCF(718,375) = HCF(8991,718) .
