HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 320, 565, 871 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 320, 565, 871 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 320, 565, 871 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 320, 565, 871 is 1.

HCF(320, 565, 871) = 1

Highest common factor (HCF) of 320, 565, 871 is 1.

Highest Common Factor of 320,565,871 using Euclid's algorithm

Highest Common Factor of 320,565,871 is 1

Step 1: Since 565 > 320, we apply the division lemma to 565 and 320, to get

565 = 320 x 1 + 245

Step 2: Since the reminder 320 ≠ 0, we apply division lemma to 245 and 320, to get

320 = 245 x 1 + 75

Step 3: We consider the new divisor 245 and the new remainder 75, and apply the division lemma to get

245 = 75 x 3 + 20

We consider the new divisor 75 and the new remainder 20,and apply the division lemma to get

75 = 20 x 3 + 15

We consider the new divisor 20 and the new remainder 15,and apply the division lemma to get

20 = 15 x 1 + 5

We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get

15 = 5 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 320 and 565 is 5

Notice that 5 = HCF(15,5) = HCF(20,15) = HCF(75,20) = HCF(245,75) = HCF(320,245) = HCF(565,320) .

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

Step 1: Since 871 > 5, we apply the division lemma to 871 and 5, to get

871 = 5 x 174 + 1

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 1 and 5, to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 871 is 1

Notice that 1 = HCF(5,1) = HCF(871,5) .
