HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 354, 665, 353 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 354, 665, 353 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 354, 665, 353 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 354, 665, 353 is 1.

HCF(354, 665, 353) = 1

HCF of 354, 665, 353 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 354, 665, 353 is 1.

Highest Common Factor of 354,665,353 using Euclid's algorithm

Highest Common Factor of 354,665,353 is 1

Step 1: Since 665 > 354, we apply the division lemma to 665 and 354, to get

665 = 354 x 1 + 311

Step 2: Since the reminder 354 ≠ 0, we apply division lemma to 311 and 354, to get

354 = 311 x 1 + 43

Step 3: We consider the new divisor 311 and the new remainder 43, and apply the division lemma to get

311 = 43 x 7 + 10

We consider the new divisor 43 and the new remainder 10,and apply the division lemma to get

43 = 10 x 4 + 3

We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get

10 = 3 x 3 + 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 354 and 665 is 1

Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(43,10) = HCF(311,43) = HCF(354,311) = HCF(665,354) .


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

Step 1: Since 353 > 1, we apply the division lemma to 353 and 1, to get

353 = 1 x 353 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 353 is 1

Notice that 1 = HCF(353,1) .
