HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 801, 9658 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 801, 9658 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 801, 9658 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 801, 9658 is 1.

HCF(801, 9658) = 1

Highest common factor (HCF) of 801, 9658 is 1.

Highest Common Factor of 801,9658 using Euclid's algorithm

Highest Common Factor of 801,9658 is 1

Step 1: Since 9658 > 801, we apply the division lemma to 9658 and 801, to get

9658 = 801 x 12 + 46

Step 2: Since the reminder 801 ≠ 0, we apply division lemma to 46 and 801, to get

801 = 46 x 17 + 19

Step 3: We consider the new divisor 46 and the new remainder 19, and apply the division lemma to get

46 = 19 x 2 + 8

We consider the new divisor 19 and the new remainder 8,and apply the division lemma to get

19 = 8 x 2 + 3

We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get

8 = 3 x 2 + 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 801 and 9658 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(19,8) = HCF(46,19) = HCF(801,46) = HCF(9658,801) .
