HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 307, 696, 345 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 307, 696, 345 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 307, 696, 345 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 307, 696, 345 is 1.

HCF(307, 696, 345) = 1

Highest common factor (HCF) of 307, 696, 345 is 1.

Highest Common Factor of 307,696,345 using Euclid's algorithm

Highest Common Factor of 307,696,345 is 1

Step 1: Since 696 > 307, we apply the division lemma to 696 and 307, to get

696 = 307 x 2 + 82

Step 2: Since the reminder 307 ≠ 0, we apply division lemma to 82 and 307, to get

307 = 82 x 3 + 61

Step 3: We consider the new divisor 82 and the new remainder 61, and apply the division lemma to get

82 = 61 x 1 + 21

We consider the new divisor 61 and the new remainder 21,and apply the division lemma to get

61 = 21 x 2 + 19

We consider the new divisor 21 and the new remainder 19,and apply the division lemma to get

21 = 19 x 1 + 2

We consider the new divisor 19 and the new remainder 2,and apply the division lemma to get

19 = 2 x 9 + 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 307 and 696 is 1

Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(21,19) = HCF(61,21) = HCF(82,61) = HCF(307,82) = HCF(696,307) .

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

Step 1: Since 345 > 1, we apply the division lemma to 345 and 1, to get

345 = 1 x 345 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 345 is 1

Notice that 1 = HCF(345,1) .
