HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 397, 676, 384 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 397, 676, 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 397, 676, 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 397, 676, 384 is 1.

HCF(397, 676, 384) = 1

HCF of 397, 676, 384 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 397, 676, 384 is 1.

Highest Common Factor of 397,676,384 using Euclid's algorithm

Highest Common Factor of 397,676,384 is 1

Step 1: Since 676 > 397, we apply the division lemma to 676 and 397, to get

676 = 397 x 1 + 279

Step 2: Since the reminder 397 ≠ 0, we apply division lemma to 279 and 397, to get

397 = 279 x 1 + 118

Step 3: We consider the new divisor 279 and the new remainder 118, and apply the division lemma to get

279 = 118 x 2 + 43

We consider the new divisor 118 and the new remainder 43,and apply the division lemma to get

118 = 43 x 2 + 32

We consider the new divisor 43 and the new remainder 32,and apply the division lemma to get

43 = 32 x 1 + 11

We consider the new divisor 32 and the new remainder 11,and apply the division lemma to get

32 = 11 x 2 + 10

We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get

11 = 10 x 1 + 1

We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get

10 = 1 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 397 and 676 is 1

Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(32,11) = HCF(43,32) = HCF(118,43) = HCF(279,118) = HCF(397,279) = HCF(676,397) .

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

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

384 = 1 x 384 + 0

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

Notice that 1 = HCF(384,1) .
