HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 318, 795, 865 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 318, 795, 865 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 318, 795, 865 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 318, 795, 865 is 1.

HCF(318, 795, 865) = 1

Highest common factor (HCF) of 318, 795, 865 is 1.

Highest Common Factor of 318,795,865 using Euclid's algorithm

Highest Common Factor of 318,795,865 is 1

Step 1: Since 795 > 318, we apply the division lemma to 795 and 318, to get

795 = 318 x 2 + 159

Step 2: Since the reminder 318 ≠ 0, we apply division lemma to 159 and 318, to get

318 = 159 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 159, the HCF of 318 and 795 is 159

Notice that 159 = HCF(318,159) = HCF(795,318) .

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

Step 1: Since 865 > 159, we apply the division lemma to 865 and 159, to get

865 = 159 x 5 + 70

Step 2: Since the reminder 159 ≠ 0, we apply division lemma to 70 and 159, to get

159 = 70 x 2 + 19

Step 3: We consider the new divisor 70 and the new remainder 19, and apply the division lemma to get

70 = 19 x 3 + 13

We consider the new divisor 19 and the new remainder 13,and apply the division lemma to get

19 = 13 x 1 + 6

We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get

13 = 6 x 2 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 159 and 865 is 1

Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(19,13) = HCF(70,19) = HCF(159,70) = HCF(865,159) .
