HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 65, 286, 307 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 65, 286, 307 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 65, 286, 307 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 65, 286, 307 is 1.

HCF(65, 286, 307) = 1

Highest common factor (HCF) of 65, 286, 307 is 1.

Highest Common Factor of 65,286,307 using Euclid's algorithm

Highest Common Factor of 65,286,307 is 1

Step 1: Since 286 > 65, we apply the division lemma to 286 and 65, to get

286 = 65 x 4 + 26

Step 2: Since the reminder 65 ≠ 0, we apply division lemma to 26 and 65, to get

65 = 26 x 2 + 13

Step 3: We consider the new divisor 26 and the new remainder 13, and apply the division lemma to get

26 = 13 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 65 and 286 is 13

Notice that 13 = HCF(26,13) = HCF(65,26) = HCF(286,65) .

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

Step 1: Since 307 > 13, we apply the division lemma to 307 and 13, to get

307 = 13 x 23 + 8

Step 2: Since the reminder 13 ≠ 0, we apply division lemma to 8 and 13, to get

13 = 8 x 1 + 5

Step 3: We consider the new divisor 8 and the new remainder 5, and apply the division lemma to get

8 = 5 x 1 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 13 and 307 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(307,13) .
