HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 169, 273, 671 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 169, 273, 671 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 169, 273, 671 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 169, 273, 671 is 1.

HCF(169, 273, 671) = 1

Highest Common Factor of 169,273,671 using Euclid's algorithm

Highest Common Factor of 169,273,671 is 1

Step 1: Since 273 > 169, we apply the division lemma to 273 and 169, to get

273 = 169 x 1 + 104

Step 2: Since the reminder 169 ≠ 0, we apply division lemma to 104 and 169, to get

169 = 104 x 1 + 65

Step 3: We consider the new divisor 104 and the new remainder 65, and apply the division lemma to get

104 = 65 x 1 + 39

We consider the new divisor 65 and the new remainder 39,and apply the division lemma to get

65 = 39 x 1 + 26

We consider the new divisor 39 and the new remainder 26,and apply the division lemma to get

39 = 26 x 1 + 13

We consider the new divisor 26 and the new remainder 13,and apply the division lemma to get

26 = 13 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 169 and 273 is 13

Notice that 13 = HCF(26,13) = HCF(39,26) = HCF(65,39) = HCF(104,65) = HCF(169,104) = HCF(273,169) .

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

Step 1: Since 671 > 13, we apply the division lemma to 671 and 13, to get

671 = 13 x 51 + 8

Step 2: Since the reminder 13 ≠ 0, we apply division lemma to 8 and 13, to get

13 = 8 x 1 + 5

Step 3: We consider the new divisor 8 and the new remainder 5, and apply the division lemma to get

8 = 5 x 1 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 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 13 and 671 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(671,13) .
