HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 322, 844, 689 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 322, 844, 689 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 322, 844, 689 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 322, 844, 689 is 1.

HCF(322, 844, 689) = 1

Highest common factor (HCF) of 322, 844, 689 is 1.

Highest Common Factor of 322,844,689 using Euclid's algorithm

Highest Common Factor of 322,844,689 is 1

Step 1: Since 844 > 322, we apply the division lemma to 844 and 322, to get

844 = 322 x 2 + 200

Step 2: Since the reminder 322 ≠ 0, we apply division lemma to 200 and 322, to get

322 = 200 x 1 + 122

Step 3: We consider the new divisor 200 and the new remainder 122, and apply the division lemma to get

200 = 122 x 1 + 78

We consider the new divisor 122 and the new remainder 78,and apply the division lemma to get

122 = 78 x 1 + 44

We consider the new divisor 78 and the new remainder 44,and apply the division lemma to get

78 = 44 x 1 + 34

We consider the new divisor 44 and the new remainder 34,and apply the division lemma to get

44 = 34 x 1 + 10

We consider the new divisor 34 and the new remainder 10,and apply the division lemma to get

34 = 10 x 3 + 4

We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get

10 = 4 x 2 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 322 and 844 is 2

Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(34,10) = HCF(44,34) = HCF(78,44) = HCF(122,78) = HCF(200,122) = HCF(322,200) = HCF(844,322) .

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

Step 1: Since 689 > 2, we apply the division lemma to 689 and 2, to get

689 = 2 x 344 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 689 is 1

Notice that 1 = HCF(2,1) = HCF(689,2) .
