HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 209, 8409 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 209, 8409 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 209, 8409 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 209, 8409 is 1.

HCF(209, 8409) = 1

Highest Common Factor of 209,8409 using Euclid's algorithm

Highest Common Factor of 209,8409 is 1

Step 1: Since 8409 > 209, we apply the division lemma to 8409 and 209, to get

8409 = 209 x 40 + 49

Step 2: Since the reminder 209 ≠ 0, we apply division lemma to 49 and 209, to get

209 = 49 x 4 + 13

Step 3: We consider the new divisor 49 and the new remainder 13, and apply the division lemma to get

49 = 13 x 3 + 10

We consider the new divisor 13 and the new remainder 10,and apply the division lemma to get

13 = 10 x 1 + 3

We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get

10 = 3 x 3 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 209 and 8409 is 1

Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(13,10) = HCF(49,13) = HCF(209,49) = HCF(8409,209) .
