HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 270, 785, 384 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 270, 785, 384 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 270, 785, 384 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 270, 785, 384 is 1.

HCF(270, 785, 384) = 1

HCF of 270, 785, 384 using Euclid's algorithm

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

Highest common factor (HCF) of 270, 785, 384 is 1.

Highest Common Factor of 270,785,384 using Euclid's algorithm

Highest Common Factor of 270,785,384 is 1

Step 1: Since 785 > 270, we apply the division lemma to 785 and 270, to get

785 = 270 x 2 + 245

Step 2: Since the reminder 270 ≠ 0, we apply division lemma to 245 and 270, to get

270 = 245 x 1 + 25

Step 3: We consider the new divisor 245 and the new remainder 25, and apply the division lemma to get

245 = 25 x 9 + 20

We consider the new divisor 25 and the new remainder 20,and apply the division lemma to get

25 = 20 x 1 + 5

We consider the new divisor 20 and the new remainder 5,and apply the division lemma to get

20 = 5 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 270 and 785 is 5

Notice that 5 = HCF(20,5) = HCF(25,20) = HCF(245,25) = HCF(270,245) = HCF(785,270) .

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

Step 1: Since 384 > 5, we apply the division lemma to 384 and 5, to get

384 = 5 x 76 + 4

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 4 and 5, to get

5 = 4 x 1 + 1

Step 3: We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 384 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(384,5) .
