HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 287, 338, 472 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 287, 338, 472 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 287, 338, 472 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 287, 338, 472 is 1.

HCF(287, 338, 472) = 1

Highest common factor (HCF) of 287, 338, 472 is 1.

Highest Common Factor of 287,338,472 using Euclid's algorithm

Highest Common Factor of 287,338,472 is 1

Step 1: Since 338 > 287, we apply the division lemma to 338 and 287, to get

338 = 287 x 1 + 51

Step 2: Since the reminder 287 ≠ 0, we apply division lemma to 51 and 287, to get

287 = 51 x 5 + 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 287 and 338 is 1

Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(19,13) = HCF(32,19) = HCF(51,32) = HCF(287,51) = HCF(338,287) .

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

Step 1: Since 472 > 1, we apply the division lemma to 472 and 1, to get

472 = 1 x 472 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 472 is 1

Notice that 1 = HCF(472,1) .
