HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 821, 9610 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 821, 9610 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 821, 9610 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 821, 9610 is 1.

HCF(821, 9610) = 1

Highest common factor (HCF) of 821, 9610 is 1.

Highest Common Factor of 821,9610 using Euclid's algorithm

Highest Common Factor of 821,9610 is 1

Step 1: Since 9610 > 821, we apply the division lemma to 9610 and 821, to get

9610 = 821 x 11 + 579

Step 2: Since the reminder 821 ≠ 0, we apply division lemma to 579 and 821, to get

821 = 579 x 1 + 242

Step 3: We consider the new divisor 579 and the new remainder 242, and apply the division lemma to get

579 = 242 x 2 + 95

We consider the new divisor 242 and the new remainder 95,and apply the division lemma to get

242 = 95 x 2 + 52

We consider the new divisor 95 and the new remainder 52,and apply the division lemma to get

95 = 52 x 1 + 43

We consider the new divisor 52 and the new remainder 43,and apply the division lemma to get

52 = 43 x 1 + 9

We consider the new divisor 43 and the new remainder 9,and apply the division lemma to get

43 = 9 x 4 + 7

We consider the new divisor 9 and the new remainder 7,and apply the division lemma to get

9 = 7 x 1 + 2

We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get

7 = 2 x 3 + 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 821 and 9610 is 1

Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(43,9) = HCF(52,43) = HCF(95,52) = HCF(242,95) = HCF(579,242) = HCF(821,579) = HCF(9610,821) .
