HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 629, 860, 165 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 629, 860, 165 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 629, 860, 165 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 629, 860, 165 is 1.

HCF(629, 860, 165) = 1

Highest common factor (HCF) of 629, 860, 165 is 1.

Highest Common Factor of 629,860,165 using Euclid's algorithm

Highest Common Factor of 629,860,165 is 1

Step 1: Since 860 > 629, we apply the division lemma to 860 and 629, to get

860 = 629 x 1 + 231

Step 2: Since the reminder 629 ≠ 0, we apply division lemma to 231 and 629, to get

629 = 231 x 2 + 167

Step 3: We consider the new divisor 231 and the new remainder 167, and apply the division lemma to get

231 = 167 x 1 + 64

We consider the new divisor 167 and the new remainder 64,and apply the division lemma to get

167 = 64 x 2 + 39

We consider the new divisor 64 and the new remainder 39,and apply the division lemma to get

64 = 39 x 1 + 25

We consider the new divisor 39 and the new remainder 25,and apply the division lemma to get

39 = 25 x 1 + 14

We consider the new divisor 25 and the new remainder 14,and apply the division lemma to get

25 = 14 x 1 + 11

We consider the new divisor 14 and the new remainder 11,and apply the division lemma to get

14 = 11 x 1 + 3

We consider the new divisor 11 and the new remainder 3,and apply the division lemma to get

11 = 3 x 3 + 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 629 and 860 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(14,11) = HCF(25,14) = HCF(39,25) = HCF(64,39) = HCF(167,64) = HCF(231,167) = HCF(629,231) = HCF(860,629) .

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

Step 1: Since 165 > 1, we apply the division lemma to 165 and 1, to get

165 = 1 x 165 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 165 is 1

Notice that 1 = HCF(165,1) .
