HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 437, 681, 309 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 437, 681, 309 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 437, 681, 309 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 437, 681, 309 is 1.

HCF(437, 681, 309) = 1

Highest Common Factor of 437,681,309 using Euclid's algorithm

Highest Common Factor of 437,681,309 is 1

Step 1: Since 681 > 437, we apply the division lemma to 681 and 437, to get

681 = 437 x 1 + 244

Step 2: Since the reminder 437 ≠ 0, we apply division lemma to 244 and 437, to get

437 = 244 x 1 + 193

Step 3: We consider the new divisor 244 and the new remainder 193, and apply the division lemma to get

244 = 193 x 1 + 51

We consider the new divisor 193 and the new remainder 51,and apply the division lemma to get

193 = 51 x 3 + 40

We consider the new divisor 51 and the new remainder 40,and apply the division lemma to get

51 = 40 x 1 + 11

We consider the new divisor 40 and the new remainder 11,and apply the division lemma to get

40 = 11 x 3 + 7

We consider the new divisor 11 and the new remainder 7,and apply the division lemma to get

11 = 7 x 1 + 4

We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get

7 = 4 x 1 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 437 and 681 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(11,7) = HCF(40,11) = HCF(51,40) = HCF(193,51) = HCF(244,193) = HCF(437,244) = HCF(681,437) .

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

Step 1: Since 309 > 1, we apply the division lemma to 309 and 1, to get

309 = 1 x 309 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 309 is 1

Notice that 1 = HCF(309,1) .
