HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 386, 838 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 386, 838 is 2 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 386, 838 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 386, 838 is 2.

HCF(386, 838) = 2

Highest common factor (HCF) of 386, 838 is 2.

Highest Common Factor of 386,838 using Euclid's algorithm

Highest Common Factor of 386,838 is 2

Step 1: Since 838 > 386, we apply the division lemma to 838 and 386, to get

838 = 386 x 2 + 66

Step 2: Since the reminder 386 ≠ 0, we apply division lemma to 66 and 386, to get

386 = 66 x 5 + 56

Step 3: We consider the new divisor 66 and the new remainder 56, and apply the division lemma to get

66 = 56 x 1 + 10

We consider the new divisor 56 and the new remainder 10,and apply the division lemma to get

56 = 10 x 5 + 6

We consider the new divisor 10 and the new remainder 6,and apply the division lemma to get

10 = 6 x 1 + 4

We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get

6 = 4 x 1 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 386 and 838 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(56,10) = HCF(66,56) = HCF(386,66) = HCF(838,386) .
