HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 486, 295, 398 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 486, 295, 398 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 486, 295, 398 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 486, 295, 398 is 1.

HCF(486, 295, 398) = 1

HCF of 486, 295, 398 using Euclid's algorithm

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

Highest common factor (HCF) of 486, 295, 398 is 1.

Highest Common Factor of 486,295,398 using Euclid's algorithm

Highest Common Factor of 486,295,398 is 1

Step 1: Since 486 > 295, we apply the division lemma to 486 and 295, to get

486 = 295 x 1 + 191

Step 2: Since the reminder 295 ≠ 0, we apply division lemma to 191 and 295, to get

295 = 191 x 1 + 104

Step 3: We consider the new divisor 191 and the new remainder 104, and apply the division lemma to get

191 = 104 x 1 + 87

We consider the new divisor 104 and the new remainder 87,and apply the division lemma to get

104 = 87 x 1 + 17

We consider the new divisor 87 and the new remainder 17,and apply the division lemma to get

87 = 17 x 5 + 2

We consider the new divisor 17 and the new remainder 2,and apply the division lemma to get

17 = 2 x 8 + 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 486 and 295 is 1

Notice that 1 = HCF(2,1) = HCF(17,2) = HCF(87,17) = HCF(104,87) = HCF(191,104) = HCF(295,191) = HCF(486,295) .

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

Step 1: Since 398 > 1, we apply the division lemma to 398 and 1, to get

398 = 1 x 398 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 398 is 1

Notice that 1 = HCF(398,1) .
