HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 730, 395, 303 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 730, 395, 303 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 730, 395, 303 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 730, 395, 303 is 1.

HCF(730, 395, 303) = 1

Highest Common Factor of 730,395,303 using Euclid's algorithm

Highest Common Factor of 730,395,303 is 1

Step 1: Since 730 > 395, we apply the division lemma to 730 and 395, to get

730 = 395 x 1 + 335

Step 2: Since the reminder 395 ≠ 0, we apply division lemma to 335 and 395, to get

395 = 335 x 1 + 60

Step 3: We consider the new divisor 335 and the new remainder 60, and apply the division lemma to get

335 = 60 x 5 + 35

We consider the new divisor 60 and the new remainder 35,and apply the division lemma to get

60 = 35 x 1 + 25

We consider the new divisor 35 and the new remainder 25,and apply the division lemma to get

35 = 25 x 1 + 10

We consider the new divisor 25 and the new remainder 10,and apply the division lemma to get

25 = 10 x 2 + 5

We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get

10 = 5 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 730 and 395 is 5

Notice that 5 = HCF(10,5) = HCF(25,10) = HCF(35,25) = HCF(60,35) = HCF(335,60) = HCF(395,335) = HCF(730,395) .

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

Step 1: Since 303 > 5, we apply the division lemma to 303 and 5, to get

303 = 5 x 60 + 3

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get

5 = 3 x 1 + 2

Step 3: 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 5 and 303 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(303,5) .
