HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 605, 328 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 605, 328 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, 328 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, 328 is 1.

HCF(605, 328) = 1

HCF of 605, 328 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 605, 328 is 1.

Highest Common Factor of 605,328 using Euclid's algorithm

Highest Common Factor of 605,328 is 1

Step 1: Since 605 > 328, we apply the division lemma to 605 and 328, to get

605 = 328 x 1 + 277

Step 2: Since the reminder 328 ≠ 0, we apply division lemma to 277 and 328, to get

328 = 277 x 1 + 51

Step 3: We consider the new divisor 277 and the new remainder 51, and apply the division lemma to get

277 = 51 x 5 + 22

We consider the new divisor 51 and the new remainder 22,and apply the division lemma to get

51 = 22 x 2 + 7

We consider the new divisor 22 and the new remainder 7,and apply the division lemma to get

22 = 7 x 3 + 1

We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get

7 = 1 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 605 and 328 is 1

Notice that 1 = HCF(7,1) = HCF(22,7) = HCF(51,22) = HCF(277,51) = HCF(328,277) = HCF(605,328) .
