HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 858, 329, 145 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 858, 329, 145 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 858, 329, 145 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 858, 329, 145 is 1.

HCF(858, 329, 145) = 1

HCF of 858, 329, 145 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 858, 329, 145 is 1.

Highest Common Factor of 858,329,145 using Euclid's algorithm

Highest Common Factor of 858,329,145 is 1

Step 1: Since 858 > 329, we apply the division lemma to 858 and 329, to get

858 = 329 x 2 + 200

Step 2: Since the reminder 329 ≠ 0, we apply division lemma to 200 and 329, to get

329 = 200 x 1 + 129

Step 3: We consider the new divisor 200 and the new remainder 129, and apply the division lemma to get

200 = 129 x 1 + 71

We consider the new divisor 129 and the new remainder 71,and apply the division lemma to get

129 = 71 x 1 + 58

We consider the new divisor 71 and the new remainder 58,and apply the division lemma to get

71 = 58 x 1 + 13

We consider the new divisor 58 and the new remainder 13,and apply the division lemma to get

58 = 13 x 4 + 6

We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get

13 = 6 x 2 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 858 and 329 is 1

Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(58,13) = HCF(71,58) = HCF(129,71) = HCF(200,129) = HCF(329,200) = HCF(858,329) .


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

Step 1: Since 145 > 1, we apply the division lemma to 145 and 1, to get

145 = 1 x 145 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 145 is 1

Notice that 1 = HCF(145,1) .
