HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 470, 388 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 470, 388 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 470, 388 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 470, 388 is 2.

HCF(470, 388) = 2

Highest common factor (HCF) of 470, 388 is 2.

Highest Common Factor of 470,388 using Euclid's algorithm

Highest Common Factor of 470,388 is 2

Step 1: Since 470 > 388, we apply the division lemma to 470 and 388, to get

470 = 388 x 1 + 82

Step 2: Since the reminder 388 ≠ 0, we apply division lemma to 82 and 388, to get

388 = 82 x 4 + 60

Step 3: We consider the new divisor 82 and the new remainder 60, and apply the division lemma to get

82 = 60 x 1 + 22

We consider the new divisor 60 and the new remainder 22,and apply the division lemma to get

60 = 22 x 2 + 16

We consider the new divisor 22 and the new remainder 16,and apply the division lemma to get

22 = 16 x 1 + 6

We consider the new divisor 16 and the new remainder 6,and apply the division lemma to get

16 = 6 x 2 + 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 470 and 388 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(16,6) = HCF(22,16) = HCF(60,22) = HCF(82,60) = HCF(388,82) = HCF(470,388) .
