HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 865, 351, 479 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 865, 351, 479 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 865, 351, 479 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 865, 351, 479 is 1.

HCF(865, 351, 479) = 1

HCF of 865, 351, 479 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 865, 351, 479 is 1.

Highest Common Factor of 865,351,479 using Euclid's algorithm

Highest Common Factor of 865,351,479 is 1

Step 1: Since 865 > 351, we apply the division lemma to 865 and 351, to get

865 = 351 x 2 + 163

Step 2: Since the reminder 351 ≠ 0, we apply division lemma to 163 and 351, to get

351 = 163 x 2 + 25

Step 3: We consider the new divisor 163 and the new remainder 25, and apply the division lemma to get

163 = 25 x 6 + 13

We consider the new divisor 25 and the new remainder 13,and apply the division lemma to get

25 = 13 x 1 + 12

We consider the new divisor 13 and the new remainder 12,and apply the division lemma to get

13 = 12 x 1 + 1

We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get

12 = 1 x 12 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 865 and 351 is 1

Notice that 1 = HCF(12,1) = HCF(13,12) = HCF(25,13) = HCF(163,25) = HCF(351,163) = HCF(865,351) .

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

Step 1: Since 479 > 1, we apply the division lemma to 479 and 1, to get

479 = 1 x 479 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 479 is 1

Notice that 1 = HCF(479,1) .
