HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 863, 497, 361 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 863, 497, 361 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 863, 497, 361 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 863, 497, 361 is 1.

HCF(863, 497, 361) = 1

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

HCF of:

Highest common factor (HCF) of 863, 497, 361 is 1.

Highest Common Factor of 863,497,361 using Euclid's algorithm

Highest Common Factor of 863,497,361 is 1

Step 1: Since 863 > 497, we apply the division lemma to 863 and 497, to get

863 = 497 x 1 + 366

Step 2: Since the reminder 497 ≠ 0, we apply division lemma to 366 and 497, to get

497 = 366 x 1 + 131

Step 3: We consider the new divisor 366 and the new remainder 131, and apply the division lemma to get

366 = 131 x 2 + 104

We consider the new divisor 131 and the new remainder 104,and apply the division lemma to get

131 = 104 x 1 + 27

We consider the new divisor 104 and the new remainder 27,and apply the division lemma to get

104 = 27 x 3 + 23

We consider the new divisor 27 and the new remainder 23,and apply the division lemma to get

27 = 23 x 1 + 4

We consider the new divisor 23 and the new remainder 4,and apply the division lemma to get

23 = 4 x 5 + 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 863 and 497 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(23,4) = HCF(27,23) = HCF(104,27) = HCF(131,104) = HCF(366,131) = HCF(497,366) = HCF(863,497) .

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

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

361 = 1 x 361 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 361 is 1

Notice that 1 = HCF(361,1) .
