HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 389, 338 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 389, 338 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 389, 338 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 389, 338 is 1.

HCF(389, 338) = 1

HCF of 389, 338 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 389, 338 is 1.

Highest Common Factor of 389,338 using Euclid's algorithm

Highest Common Factor of 389,338 is 1

Step 1: Since 389 > 338, we apply the division lemma to 389 and 338, to get

389 = 338 x 1 + 51

Step 2: Since the reminder 338 ≠ 0, we apply division lemma to 51 and 338, to get

338 = 51 x 6 + 32

Step 3: We consider the new divisor 51 and the new remainder 32, and apply the division lemma to get

51 = 32 x 1 + 19

We consider the new divisor 32 and the new remainder 19,and apply the division lemma to get

32 = 19 x 1 + 13

We consider the new divisor 19 and the new remainder 13,and apply the division lemma to get

19 = 13 x 1 + 6

We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get

13 = 6 x 2 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 389 and 338 is 1

Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(19,13) = HCF(32,19) = HCF(51,32) = HCF(338,51) = HCF(389,338) .
