HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 315, 590, 422 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 315, 590, 422 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 315, 590, 422 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 315, 590, 422 is 1.

HCF(315, 590, 422) = 1

HCF of 315, 590, 422 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 315, 590, 422 is 1.

Highest Common Factor of 315,590,422 using Euclid's algorithm

Highest Common Factor of 315,590,422 is 1

Step 1: Since 590 > 315, we apply the division lemma to 590 and 315, to get

590 = 315 x 1 + 275

Step 2: Since the reminder 315 ≠ 0, we apply division lemma to 275 and 315, to get

315 = 275 x 1 + 40

Step 3: We consider the new divisor 275 and the new remainder 40, and apply the division lemma to get

275 = 40 x 6 + 35

We consider the new divisor 40 and the new remainder 35,and apply the division lemma to get

40 = 35 x 1 + 5

We consider the new divisor 35 and the new remainder 5,and apply the division lemma to get

35 = 5 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 315 and 590 is 5

Notice that 5 = HCF(35,5) = HCF(40,35) = HCF(275,40) = HCF(315,275) = HCF(590,315) .

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

Step 1: Since 422 > 5, we apply the division lemma to 422 and 5, to get

422 = 5 x 84 + 2

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 2 and 5, to get

5 = 2 x 2 + 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 5 and 422 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(422,5) .
