HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 394, 655, 608 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 394, 655, 608 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, 655, 608 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, 655, 608 is 1.

HCF(394, 655, 608) = 1

HCF of 394, 655, 608 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, 655, 608 is 1.

Highest Common Factor of 394,655,608 using Euclid's algorithm

Highest Common Factor of 394,655,608 is 1

Step 1: Since 655 > 394, we apply the division lemma to 655 and 394, to get

655 = 394 x 1 + 261

Step 2: Since the reminder 394 ≠ 0, we apply division lemma to 261 and 394, to get

394 = 261 x 1 + 133

Step 3: We consider the new divisor 261 and the new remainder 133, and apply the division lemma to get

261 = 133 x 1 + 128

We consider the new divisor 133 and the new remainder 128,and apply the division lemma to get

133 = 128 x 1 + 5

We consider the new divisor 128 and the new remainder 5,and apply the division lemma to get

128 = 5 x 25 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 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 394 and 655 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(128,5) = HCF(133,128) = HCF(261,133) = HCF(394,261) = HCF(655,394) .

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

Step 1: Since 608 > 1, we apply the division lemma to 608 and 1, to get

608 = 1 x 608 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 608 is 1

Notice that 1 = HCF(608,1) .
