HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 351, 129, 371 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 351, 129, 371 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 351, 129, 371 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 351, 129, 371 is 1.

HCF(351, 129, 371) = 1

Highest common factor (HCF) of 351, 129, 371 is 1.

Highest Common Factor of 351,129,371 using Euclid's algorithm

Highest Common Factor of 351,129,371 is 1

Step 1: Since 351 > 129, we apply the division lemma to 351 and 129, to get

351 = 129 x 2 + 93

Step 2: Since the reminder 129 ≠ 0, we apply division lemma to 93 and 129, to get

129 = 93 x 1 + 36

Step 3: We consider the new divisor 93 and the new remainder 36, and apply the division lemma to get

93 = 36 x 2 + 21

We consider the new divisor 36 and the new remainder 21,and apply the division lemma to get

36 = 21 x 1 + 15

We consider the new divisor 21 and the new remainder 15,and apply the division lemma to get

21 = 15 x 1 + 6

We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get

15 = 6 x 2 + 3

We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 351 and 129 is 3

Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(21,15) = HCF(36,21) = HCF(93,36) = HCF(129,93) = HCF(351,129) .

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

Step 1: Since 371 > 3, we apply the division lemma to 371 and 3, to get

371 = 3 x 123 + 2

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get

3 = 2 x 1 + 1

Step 3: 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 3 and 371 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(371,3) .
