HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 913, 9798 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 913, 9798 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 913, 9798 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 913, 9798 is 1.

HCF(913, 9798) = 1

Highest common factor (HCF) of 913, 9798 is 1.

Highest Common Factor of 913,9798 using Euclid's algorithm

Highest Common Factor of 913,9798 is 1

Step 1: Since 9798 > 913, we apply the division lemma to 9798 and 913, to get

9798 = 913 x 10 + 668

Step 2: Since the reminder 913 ≠ 0, we apply division lemma to 668 and 913, to get

913 = 668 x 1 + 245

Step 3: We consider the new divisor 668 and the new remainder 245, and apply the division lemma to get

668 = 245 x 2 + 178

We consider the new divisor 245 and the new remainder 178,and apply the division lemma to get

245 = 178 x 1 + 67

We consider the new divisor 178 and the new remainder 67,and apply the division lemma to get

178 = 67 x 2 + 44

We consider the new divisor 67 and the new remainder 44,and apply the division lemma to get

67 = 44 x 1 + 23

We consider the new divisor 44 and the new remainder 23,and apply the division lemma to get

44 = 23 x 1 + 21

We consider the new divisor 23 and the new remainder 21,and apply the division lemma to get

23 = 21 x 1 + 2

We consider the new divisor 21 and the new remainder 2,and apply the division lemma to get

21 = 2 x 10 + 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 913 and 9798 is 1

Notice that 1 = HCF(2,1) = HCF(21,2) = HCF(23,21) = HCF(44,23) = HCF(67,44) = HCF(178,67) = HCF(245,178) = HCF(668,245) = HCF(913,668) = HCF(9798,913) .
