HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 387, 713, 472 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 387, 713, 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 387, 713, 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 387, 713, 472 is 1.

HCF(387, 713, 472) = 1

Highest common factor (HCF) of 387, 713, 472 is 1.

Highest Common Factor of 387,713,472 using Euclid's algorithm

Highest Common Factor of 387,713,472 is 1

Step 1: Since 713 > 387, we apply the division lemma to 713 and 387, to get

713 = 387 x 1 + 326

Step 2: Since the reminder 387 ≠ 0, we apply division lemma to 326 and 387, to get

387 = 326 x 1 + 61

Step 3: We consider the new divisor 326 and the new remainder 61, and apply the division lemma to get

326 = 61 x 5 + 21

We consider the new divisor 61 and the new remainder 21,and apply the division lemma to get

61 = 21 x 2 + 19

We consider the new divisor 21 and the new remainder 19,and apply the division lemma to get

21 = 19 x 1 + 2

We consider the new divisor 19 and the new remainder 2,and apply the division lemma to get

19 = 2 x 9 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 387 and 713 is 1

Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(21,19) = HCF(61,21) = HCF(326,61) = HCF(387,326) = HCF(713,387) .

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) .
