HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 405, 701, 382 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 405, 701, 382 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 405, 701, 382 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 405, 701, 382 is 1.

HCF(405, 701, 382) = 1

HCF of 405, 701, 382 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 405, 701, 382 is 1.

Highest Common Factor of 405,701,382 using Euclid's algorithm

Highest Common Factor of 405,701,382 is 1

Step 1: Since 701 > 405, we apply the division lemma to 701 and 405, to get

701 = 405 x 1 + 296

Step 2: Since the reminder 405 ≠ 0, we apply division lemma to 296 and 405, to get

405 = 296 x 1 + 109

Step 3: We consider the new divisor 296 and the new remainder 109, and apply the division lemma to get

296 = 109 x 2 + 78

We consider the new divisor 109 and the new remainder 78,and apply the division lemma to get

109 = 78 x 1 + 31

We consider the new divisor 78 and the new remainder 31,and apply the division lemma to get

78 = 31 x 2 + 16

We consider the new divisor 31 and the new remainder 16,and apply the division lemma to get

31 = 16 x 1 + 15

We consider the new divisor 16 and the new remainder 15,and apply the division lemma to get

16 = 15 x 1 + 1

We consider the new divisor 15 and the new remainder 1,and apply the division lemma to get

15 = 1 x 15 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 405 and 701 is 1

Notice that 1 = HCF(15,1) = HCF(16,15) = HCF(31,16) = HCF(78,31) = HCF(109,78) = HCF(296,109) = HCF(405,296) = HCF(701,405) .

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

Step 1: Since 382 > 1, we apply the division lemma to 382 and 1, to get

382 = 1 x 382 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 382 is 1

Notice that 1 = HCF(382,1) .
