HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 694, 355, 803 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 694, 355, 803 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 694, 355, 803 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 694, 355, 803 is 1.

HCF(694, 355, 803) = 1

HCF of 694, 355, 803 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 694, 355, 803 is 1.

Highest Common Factor of 694,355,803 using Euclid's algorithm

Highest Common Factor of 694,355,803 is 1

Step 1: Since 694 > 355, we apply the division lemma to 694 and 355, to get

694 = 355 x 1 + 339

Step 2: Since the reminder 355 ≠ 0, we apply division lemma to 339 and 355, to get

355 = 339 x 1 + 16

Step 3: We consider the new divisor 339 and the new remainder 16, and apply the division lemma to get

339 = 16 x 21 + 3

We consider the new divisor 16 and the new remainder 3,and apply the division lemma to get

16 = 3 x 5 + 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 694 and 355 is 1

Notice that 1 = HCF(3,1) = HCF(16,3) = HCF(339,16) = HCF(355,339) = HCF(694,355) .


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

Step 1: Since 803 > 1, we apply the division lemma to 803 and 1, to get

803 = 1 x 803 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 803 is 1

Notice that 1 = HCF(803,1) .
