HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 605, 356, 643, 518 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 605, 356, 643, 518 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 605, 356, 643, 518 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 605, 356, 643, 518 is 1.

HCF(605, 356, 643, 518) = 1

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

HCF of:

Highest common factor (HCF) of 605, 356, 643, 518 is 1.

Highest Common Factor of 605,356,643,518 using Euclid's algorithm

Highest Common Factor of 605,356,643,518 is 1

Step 1: Since 605 > 356, we apply the division lemma to 605 and 356, to get

605 = 356 x 1 + 249

Step 2: Since the reminder 356 ≠ 0, we apply division lemma to 249 and 356, to get

356 = 249 x 1 + 107

Step 3: We consider the new divisor 249 and the new remainder 107, and apply the division lemma to get

249 = 107 x 2 + 35

We consider the new divisor 107 and the new remainder 35,and apply the division lemma to get

107 = 35 x 3 + 2

We consider the new divisor 35 and the new remainder 2,and apply the division lemma to get

35 = 2 x 17 + 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 605 and 356 is 1

Notice that 1 = HCF(2,1) = HCF(35,2) = HCF(107,35) = HCF(249,107) = HCF(356,249) = HCF(605,356) .


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

Step 1: Since 643 > 1, we apply the division lemma to 643 and 1, to get

643 = 1 x 643 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 643 is 1

Notice that 1 = HCF(643,1) .


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

Step 1: Since 518 > 1, we apply the division lemma to 518 and 1, to get

518 = 1 x 518 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 518 is 1

Notice that 1 = HCF(518,1) .
