HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 394, 695, 18 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 394, 695, 18 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 394, 695, 18 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 394, 695, 18 is 1.

HCF(394, 695, 18) = 1

HCF of 394, 695, 18 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 394, 695, 18 is 1.

Highest Common Factor of 394,695,18 using Euclid's algorithm

Highest Common Factor of 394,695,18 is 1

Step 1: Since 695 > 394, we apply the division lemma to 695 and 394, to get

695 = 394 x 1 + 301

Step 2: Since the reminder 394 ≠ 0, we apply division lemma to 301 and 394, to get

394 = 301 x 1 + 93

Step 3: We consider the new divisor 301 and the new remainder 93, and apply the division lemma to get

301 = 93 x 3 + 22

We consider the new divisor 93 and the new remainder 22,and apply the division lemma to get

93 = 22 x 4 + 5

We consider the new divisor 22 and the new remainder 5,and apply the division lemma to get

22 = 5 x 4 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 394 and 695 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(22,5) = HCF(93,22) = HCF(301,93) = HCF(394,301) = HCF(695,394) .

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

Step 1: Since 18 > 1, we apply the division lemma to 18 and 1, to get

18 = 1 x 18 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 18 is 1

Notice that 1 = HCF(18,1) .
