HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 324, 395, 678 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 324, 395, 678 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 324, 395, 678 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 324, 395, 678 is 1.

HCF(324, 395, 678) = 1

HCF of 324, 395, 678 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 324, 395, 678 is 1.

Highest Common Factor of 324,395,678 using Euclid's algorithm

Highest Common Factor of 324,395,678 is 1

Step 1: Since 395 > 324, we apply the division lemma to 395 and 324, to get

395 = 324 x 1 + 71

Step 2: Since the reminder 324 ≠ 0, we apply division lemma to 71 and 324, to get

324 = 71 x 4 + 40

Step 3: We consider the new divisor 71 and the new remainder 40, and apply the division lemma to get

71 = 40 x 1 + 31

We consider the new divisor 40 and the new remainder 31,and apply the division lemma to get

40 = 31 x 1 + 9

We consider the new divisor 31 and the new remainder 9,and apply the division lemma to get

31 = 9 x 3 + 4

We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get

9 = 4 x 2 + 1

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 324 and 395 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(31,9) = HCF(40,31) = HCF(71,40) = HCF(324,71) = HCF(395,324) .

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

Step 1: Since 678 > 1, we apply the division lemma to 678 and 1, to get

678 = 1 x 678 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 678 is 1

Notice that 1 = HCF(678,1) .
