HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 689, 930, 330 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 689, 930, 330 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 689, 930, 330 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 689, 930, 330 is 1.

HCF(689, 930, 330) = 1

HCF of 689, 930, 330 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 689, 930, 330 is 1.

Highest Common Factor of 689,930,330 using Euclid's algorithm

Highest Common Factor of 689,930,330 is 1

Step 1: Since 930 > 689, we apply the division lemma to 930 and 689, to get

930 = 689 x 1 + 241

Step 2: Since the reminder 689 ≠ 0, we apply division lemma to 241 and 689, to get

689 = 241 x 2 + 207

Step 3: We consider the new divisor 241 and the new remainder 207, and apply the division lemma to get

241 = 207 x 1 + 34

We consider the new divisor 207 and the new remainder 34,and apply the division lemma to get

207 = 34 x 6 + 3

We consider the new divisor 34 and the new remainder 3,and apply the division lemma to get

34 = 3 x 11 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 689 and 930 is 1

Notice that 1 = HCF(3,1) = HCF(34,3) = HCF(207,34) = HCF(241,207) = HCF(689,241) = HCF(930,689) .

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

Step 1: Since 330 > 1, we apply the division lemma to 330 and 1, to get

330 = 1 x 330 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 330 is 1

Notice that 1 = HCF(330,1) .
