HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 723, 402, 383 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 723, 402, 383 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 723, 402, 383 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 723, 402, 383 is 1.

HCF(723, 402, 383) = 1

Highest common factor (HCF) of 723, 402, 383 is 1.

Highest Common Factor of 723,402,383 using Euclid's algorithm

Highest Common Factor of 723,402,383 is 1

Step 1: Since 723 > 402, we apply the division lemma to 723 and 402, to get

723 = 402 x 1 + 321

Step 2: Since the reminder 402 ≠ 0, we apply division lemma to 321 and 402, to get

402 = 321 x 1 + 81

Step 3: We consider the new divisor 321 and the new remainder 81, and apply the division lemma to get

321 = 81 x 3 + 78

We consider the new divisor 81 and the new remainder 78,and apply the division lemma to get

81 = 78 x 1 + 3

We consider the new divisor 78 and the new remainder 3,and apply the division lemma to get

78 = 3 x 26 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 723 and 402 is 3

Notice that 3 = HCF(78,3) = HCF(81,78) = HCF(321,81) = HCF(402,321) = HCF(723,402) .

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

Step 1: Since 383 > 3, we apply the division lemma to 383 and 3, to get

383 = 3 x 127 + 2

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get

3 = 2 x 1 + 1

Step 3: 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 3 and 383 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(383,3) .
