HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 404, 255, 394 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 404, 255, 394 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 404, 255, 394 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 404, 255, 394 is 1.

HCF(404, 255, 394) = 1

Highest common factor (HCF) of 404, 255, 394 is 1.

Highest Common Factor of 404,255,394 using Euclid's algorithm

Highest Common Factor of 404,255,394 is 1

Step 1: Since 404 > 255, we apply the division lemma to 404 and 255, to get

404 = 255 x 1 + 149

Step 2: Since the reminder 255 ≠ 0, we apply division lemma to 149 and 255, to get

255 = 149 x 1 + 106

Step 3: We consider the new divisor 149 and the new remainder 106, and apply the division lemma to get

149 = 106 x 1 + 43

We consider the new divisor 106 and the new remainder 43,and apply the division lemma to get

106 = 43 x 2 + 20

We consider the new divisor 43 and the new remainder 20,and apply the division lemma to get

43 = 20 x 2 + 3

We consider the new divisor 20 and the new remainder 3,and apply the division lemma to get

20 = 3 x 6 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 404 and 255 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(20,3) = HCF(43,20) = HCF(106,43) = HCF(149,106) = HCF(255,149) = HCF(404,255) .


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

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

394 = 1 x 394 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 394 is 1

Notice that 1 = HCF(394,1) .
