HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 487, 376, 743 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 487, 376, 743 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 487, 376, 743 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 487, 376, 743 is 1.

HCF(487, 376, 743) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 487, 376, 743 is 1.

Highest Common Factor of 487,376,743 using Euclid's algorithm

Highest Common Factor of 487,376,743 is 1

Step 1: Since 487 > 376, we apply the division lemma to 487 and 376, to get

487 = 376 x 1 + 111

Step 2: Since the reminder 376 ≠ 0, we apply division lemma to 111 and 376, to get

376 = 111 x 3 + 43

Step 3: We consider the new divisor 111 and the new remainder 43, and apply the division lemma to get

111 = 43 x 2 + 25

We consider the new divisor 43 and the new remainder 25,and apply the division lemma to get

43 = 25 x 1 + 18

We consider the new divisor 25 and the new remainder 18,and apply the division lemma to get

25 = 18 x 1 + 7

We consider the new divisor 18 and the new remainder 7,and apply the division lemma to get

18 = 7 x 2 + 4

We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get

7 = 4 x 1 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 487 and 376 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(18,7) = HCF(25,18) = HCF(43,25) = HCF(111,43) = HCF(376,111) = HCF(487,376) .

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

Step 1: Since 743 > 1, we apply the division lemma to 743 and 1, to get

743 = 1 x 743 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 743 is 1

Notice that 1 = HCF(743,1) .
