HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 355, 601, 678 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 355, 601, 678 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 355, 601, 678 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 355, 601, 678 is 1.

HCF(355, 601, 678) = 1

HCF of 355, 601, 678 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

Highest common factor (HCF) of 355, 601, 678 is 1.

Highest Common Factor of 355,601,678 using Euclid's algorithm

Highest Common Factor of 355,601,678 is 1

Step 1: Since 601 > 355, we apply the division lemma to 601 and 355, to get

601 = 355 x 1 + 246

Step 2: Since the reminder 355 ≠ 0, we apply division lemma to 246 and 355, to get

355 = 246 x 1 + 109

Step 3: We consider the new divisor 246 and the new remainder 109, and apply the division lemma to get

246 = 109 x 2 + 28

We consider the new divisor 109 and the new remainder 28,and apply the division lemma to get

109 = 28 x 3 + 25

We consider the new divisor 28 and the new remainder 25,and apply the division lemma to get

28 = 25 x 1 + 3

We consider the new divisor 25 and the new remainder 3,and apply the division lemma to get

25 = 3 x 8 + 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 355 and 601 is 1

Notice that 1 = HCF(3,1) = HCF(25,3) = HCF(28,25) = HCF(109,28) = HCF(246,109) = HCF(355,246) = HCF(601,355) .

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

Step 1: Since 678 > 1, we apply the division lemma to 678 and 1, to get

678 = 1 x 678 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 678 is 1

Notice that 1 = HCF(678,1) .
