HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 247, 423, 335 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 247, 423, 335 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 247, 423, 335 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 247, 423, 335 is 1.

HCF(247, 423, 335) = 1

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

HCF of:

Highest common factor (HCF) of 247, 423, 335 is 1.

Highest Common Factor of 247,423,335 using Euclid's algorithm

Highest Common Factor of 247,423,335 is 1

Step 1: Since 423 > 247, we apply the division lemma to 423 and 247, to get

423 = 247 x 1 + 176

Step 2: Since the reminder 247 ≠ 0, we apply division lemma to 176 and 247, to get

247 = 176 x 1 + 71

Step 3: We consider the new divisor 176 and the new remainder 71, and apply the division lemma to get

176 = 71 x 2 + 34

We consider the new divisor 71 and the new remainder 34,and apply the division lemma to get

71 = 34 x 2 + 3

We consider the new divisor 34 and the new remainder 3,and apply the division lemma to get

34 = 3 x 11 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 247 and 423 is 1

Notice that 1 = HCF(3,1) = HCF(34,3) = HCF(71,34) = HCF(176,71) = HCF(247,176) = HCF(423,247) .

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

Step 1: Since 335 > 1, we apply the division lemma to 335 and 1, to get

335 = 1 x 335 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 335 is 1

Notice that 1 = HCF(335,1) .
