HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 393, 614, 855 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 393, 614, 855 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 393, 614, 855 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 393, 614, 855 is 1.

HCF(393, 614, 855) = 1

HCF of 393, 614, 855 using Euclid's algorithm

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

Highest common factor (HCF) of 393, 614, 855 is 1.

Highest Common Factor of 393,614,855 using Euclid's algorithm

Highest Common Factor of 393,614,855 is 1

Step 1: Since 614 > 393, we apply the division lemma to 614 and 393, to get

614 = 393 x 1 + 221

Step 2: Since the reminder 393 ≠ 0, we apply division lemma to 221 and 393, to get

393 = 221 x 1 + 172

Step 3: We consider the new divisor 221 and the new remainder 172, and apply the division lemma to get

221 = 172 x 1 + 49

We consider the new divisor 172 and the new remainder 49,and apply the division lemma to get

172 = 49 x 3 + 25

We consider the new divisor 49 and the new remainder 25,and apply the division lemma to get

49 = 25 x 1 + 24

We consider the new divisor 25 and the new remainder 24,and apply the division lemma to get

25 = 24 x 1 + 1

We consider the new divisor 24 and the new remainder 1,and apply the division lemma to get

24 = 1 x 24 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 393 and 614 is 1

Notice that 1 = HCF(24,1) = HCF(25,24) = HCF(49,25) = HCF(172,49) = HCF(221,172) = HCF(393,221) = HCF(614,393) .

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

Step 1: Since 855 > 1, we apply the division lemma to 855 and 1, to get

855 = 1 x 855 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 855 is 1

Notice that 1 = HCF(855,1) .
