HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 209, 4971, 5305 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 209, 4971, 5305 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, 4971, 5305 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, 4971, 5305 is 1.

HCF(209, 4971, 5305) = 1

Highest common factor (HCF) of 209, 4971, 5305 is 1.

Highest Common Factor of 209,4971,5305 using Euclid's algorithm

Highest Common Factor of 209,4971,5305 is 1

Step 1: Since 4971 > 209, we apply the division lemma to 4971 and 209, to get

4971 = 209 x 23 + 164

Step 2: Since the reminder 209 ≠ 0, we apply division lemma to 164 and 209, to get

209 = 164 x 1 + 45

Step 3: We consider the new divisor 164 and the new remainder 45, and apply the division lemma to get

164 = 45 x 3 + 29

We consider the new divisor 45 and the new remainder 29,and apply the division lemma to get

45 = 29 x 1 + 16

We consider the new divisor 29 and the new remainder 16,and apply the division lemma to get

29 = 16 x 1 + 13

We consider the new divisor 16 and the new remainder 13,and apply the division lemma to get

16 = 13 x 1 + 3

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

13 = 3 x 4 + 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 4971 is 1

Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(16,13) = HCF(29,16) = HCF(45,29) = HCF(164,45) = HCF(209,164) = HCF(4971,209) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 5305 > 1, we apply the division lemma to 5305 and 1, to get

5305 = 1 x 5305 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 5305 is 1

Notice that 1 = HCF(5305,1) .
