HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 361, 982, 494 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 361, 982, 494 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 361, 982, 494 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 361, 982, 494 is 1.

HCF(361, 982, 494) = 1

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

HCF of:

Highest common factor (HCF) of 361, 982, 494 is 1.

Highest Common Factor of 361,982,494 using Euclid's algorithm

Highest Common Factor of 361,982,494 is 1

Step 1: Since 982 > 361, we apply the division lemma to 982 and 361, to get

982 = 361 x 2 + 260

Step 2: Since the reminder 361 ≠ 0, we apply division lemma to 260 and 361, to get

361 = 260 x 1 + 101

Step 3: We consider the new divisor 260 and the new remainder 101, and apply the division lemma to get

260 = 101 x 2 + 58

We consider the new divisor 101 and the new remainder 58,and apply the division lemma to get

101 = 58 x 1 + 43

We consider the new divisor 58 and the new remainder 43,and apply the division lemma to get

58 = 43 x 1 + 15

We consider the new divisor 43 and the new remainder 15,and apply the division lemma to get

43 = 15 x 2 + 13

We consider the new divisor 15 and the new remainder 13,and apply the division lemma to get

15 = 13 x 1 + 2

We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get

13 = 2 x 6 + 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 361 and 982 is 1

Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(15,13) = HCF(43,15) = HCF(58,43) = HCF(101,58) = HCF(260,101) = HCF(361,260) = HCF(982,361) .

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

Step 1: Since 494 > 1, we apply the division lemma to 494 and 1, to get

494 = 1 x 494 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 494 is 1

Notice that 1 = HCF(494,1) .
