HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 651, 376, 309 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 651, 376, 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 651, 376, 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 651, 376, 309 is 1.

HCF(651, 376, 309) = 1

Highest common factor (HCF) of 651, 376, 309 is 1.

Highest Common Factor of 651,376,309 using Euclid's algorithm

Highest Common Factor of 651,376,309 is 1

Step 1: Since 651 > 376, we apply the division lemma to 651 and 376, to get

651 = 376 x 1 + 275

Step 2: Since the reminder 376 ≠ 0, we apply division lemma to 275 and 376, to get

376 = 275 x 1 + 101

Step 3: We consider the new divisor 275 and the new remainder 101, and apply the division lemma to get

275 = 101 x 2 + 73

We consider the new divisor 101 and the new remainder 73,and apply the division lemma to get

101 = 73 x 1 + 28

We consider the new divisor 73 and the new remainder 28,and apply the division lemma to get

73 = 28 x 2 + 17

We consider the new divisor 28 and the new remainder 17,and apply the division lemma to get

28 = 17 x 1 + 11

We consider the new divisor 17 and the new remainder 11,and apply the division lemma to get

17 = 11 x 1 + 6

We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get

11 = 6 x 1 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 651 and 376 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(17,11) = HCF(28,17) = HCF(73,28) = HCF(101,73) = HCF(275,101) = HCF(376,275) = HCF(651,376) .

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) .
