HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 321, 642, 529 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 321, 642, 529 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 321, 642, 529 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 321, 642, 529 is 1.

HCF(321, 642, 529) = 1

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

HCF of:

Highest common factor (HCF) of 321, 642, 529 is 1.

Highest Common Factor of 321,642,529 using Euclid's algorithm

Highest Common Factor of 321,642,529 is 1

Step 1: Since 642 > 321, we apply the division lemma to 642 and 321, to get

642 = 321 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 321, the HCF of 321 and 642 is 321

Notice that 321 = HCF(642,321) .

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

Step 1: Since 529 > 321, we apply the division lemma to 529 and 321, to get

529 = 321 x 1 + 208

Step 2: Since the reminder 321 ≠ 0, we apply division lemma to 208 and 321, to get

321 = 208 x 1 + 113

Step 3: We consider the new divisor 208 and the new remainder 113, and apply the division lemma to get

208 = 113 x 1 + 95

We consider the new divisor 113 and the new remainder 95,and apply the division lemma to get

113 = 95 x 1 + 18

We consider the new divisor 95 and the new remainder 18,and apply the division lemma to get

95 = 18 x 5 + 5

We consider the new divisor 18 and the new remainder 5,and apply the division lemma to get

18 = 5 x 3 + 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 321 and 529 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(18,5) = HCF(95,18) = HCF(113,95) = HCF(208,113) = HCF(321,208) = HCF(529,321) .
