HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 351, 998, 830 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 351, 998, 830 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, 998, 830 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, 998, 830 is 1.

HCF(351, 998, 830) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 351, 998, 830 is 1.

Highest Common Factor of 351,998,830 using Euclid's algorithm

Highest Common Factor of 351,998,830 is 1

Step 1: Since 998 > 351, we apply the division lemma to 998 and 351, to get

998 = 351 x 2 + 296

Step 2: Since the reminder 351 ≠ 0, we apply division lemma to 296 and 351, to get

351 = 296 x 1 + 55

Step 3: We consider the new divisor 296 and the new remainder 55, and apply the division lemma to get

296 = 55 x 5 + 21

We consider the new divisor 55 and the new remainder 21,and apply the division lemma to get

55 = 21 x 2 + 13

We consider the new divisor 21 and the new remainder 13,and apply the division lemma to get

21 = 13 x 1 + 8

We consider the new divisor 13 and the new remainder 8,and apply the division lemma to get

13 = 8 x 1 + 5

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 351 and 998 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(21,13) = HCF(55,21) = HCF(296,55) = HCF(351,296) = HCF(998,351) .

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

Step 1: Since 830 > 1, we apply the division lemma to 830 and 1, to get

830 = 1 x 830 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 830 is 1

Notice that 1 = HCF(830,1) .
