HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 748, 470, 386 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 748, 470, 386 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 748, 470, 386 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 748, 470, 386 is 2.

HCF(748, 470, 386) = 2

Highest Common Factor of 748,470,386 using Euclid's algorithm

Highest Common Factor of 748,470,386 is 2

Step 1: Since 748 > 470, we apply the division lemma to 748 and 470, to get

748 = 470 x 1 + 278

Step 2: Since the reminder 470 ≠ 0, we apply division lemma to 278 and 470, to get

470 = 278 x 1 + 192

Step 3: We consider the new divisor 278 and the new remainder 192, and apply the division lemma to get

278 = 192 x 1 + 86

We consider the new divisor 192 and the new remainder 86,and apply the division lemma to get

192 = 86 x 2 + 20

We consider the new divisor 86 and the new remainder 20,and apply the division lemma to get

86 = 20 x 4 + 6

We consider the new divisor 20 and the new remainder 6,and apply the division lemma to get

20 = 6 x 3 + 2

We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get

6 = 2 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 748 and 470 is 2

Notice that 2 = HCF(6,2) = HCF(20,6) = HCF(86,20) = HCF(192,86) = HCF(278,192) = HCF(470,278) = HCF(748,470) .

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

Step 1: Since 386 > 2, we apply the division lemma to 386 and 2, to get

386 = 2 x 193 + 0

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

Notice that 2 = HCF(386,2) .
