HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 323, 665 i.e. 19 the largest integer that leaves a remainder zero for all numbers.

HCF of 323, 665 is 19 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 323, 665 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 323, 665 is 19.

HCF(323, 665) = 19

HCF of 323, 665 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 323, 665 is 19.

Highest Common Factor of 323,665 using Euclid's algorithm

Highest Common Factor of 323,665 is 19

Step 1: Since 665 > 323, we apply the division lemma to 665 and 323, to get

665 = 323 x 2 + 19

Step 2: Since the reminder 323 ≠ 0, we apply division lemma to 19 and 323, to get

323 = 19 x 17 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 19, the HCF of 323 and 665 is 19

Notice that 19 = HCF(323,19) = HCF(665,323) .
