HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 995, 607, 405 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 995, 607, 405 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 995, 607, 405 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 995, 607, 405 is 1.

HCF(995, 607, 405) = 1

Highest common factor (HCF) of 995, 607, 405 is 1.

Highest Common Factor of 995,607,405 using Euclid's algorithm

Highest Common Factor of 995,607,405 is 1

Step 1: Since 995 > 607, we apply the division lemma to 995 and 607, to get

995 = 607 x 1 + 388

Step 2: Since the reminder 607 ≠ 0, we apply division lemma to 388 and 607, to get

607 = 388 x 1 + 219

Step 3: We consider the new divisor 388 and the new remainder 219, and apply the division lemma to get

388 = 219 x 1 + 169

We consider the new divisor 219 and the new remainder 169,and apply the division lemma to get

219 = 169 x 1 + 50

We consider the new divisor 169 and the new remainder 50,and apply the division lemma to get

169 = 50 x 3 + 19

We consider the new divisor 50 and the new remainder 19,and apply the division lemma to get

50 = 19 x 2 + 12

We consider the new divisor 19 and the new remainder 12,and apply the division lemma to get

19 = 12 x 1 + 7

We consider the new divisor 12 and the new remainder 7,and apply the division lemma to get

12 = 7 x 1 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 995 and 607 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(12,7) = HCF(19,12) = HCF(50,19) = HCF(169,50) = HCF(219,169) = HCF(388,219) = HCF(607,388) = HCF(995,607) .

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

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

405 = 1 x 405 + 0

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

Notice that 1 = HCF(405,1) .
