HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 397, 4343, 3365 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 397, 4343, 3365 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 397, 4343, 3365 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 397, 4343, 3365 is 1.

HCF(397, 4343, 3365) = 1

Highest common factor (HCF) of 397, 4343, 3365 is 1.

Highest Common Factor of 397,4343,3365 using Euclid's algorithm

Highest Common Factor of 397,4343,3365 is 1

Step 1: Since 4343 > 397, we apply the division lemma to 4343 and 397, to get

4343 = 397 x 10 + 373

Step 2: Since the reminder 397 ≠ 0, we apply division lemma to 373 and 397, to get

397 = 373 x 1 + 24

Step 3: We consider the new divisor 373 and the new remainder 24, and apply the division lemma to get

373 = 24 x 15 + 13

We consider the new divisor 24 and the new remainder 13,and apply the division lemma to get

24 = 13 x 1 + 11

We consider the new divisor 13 and the new remainder 11,and apply the division lemma to get

13 = 11 x 1 + 2

We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get

11 = 2 x 5 + 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 397 and 4343 is 1

Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(13,11) = HCF(24,13) = HCF(373,24) = HCF(397,373) = HCF(4343,397) .

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

Step 1: Since 3365 > 1, we apply the division lemma to 3365 and 1, to get

3365 = 1 x 3365 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 3365 is 1

Notice that 1 = HCF(3365,1) .
