HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 198, 362, 873 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 198, 362, 873 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 198, 362, 873 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 198, 362, 873 is 1.

HCF(198, 362, 873) = 1

Highest common factor (HCF) of 198, 362, 873 is 1.

Highest Common Factor of 198,362,873 using Euclid's algorithm

Highest Common Factor of 198,362,873 is 1

Step 1: Since 362 > 198, we apply the division lemma to 362 and 198, to get

362 = 198 x 1 + 164

Step 2: Since the reminder 198 ≠ 0, we apply division lemma to 164 and 198, to get

198 = 164 x 1 + 34

Step 3: We consider the new divisor 164 and the new remainder 34, and apply the division lemma to get

164 = 34 x 4 + 28

We consider the new divisor 34 and the new remainder 28,and apply the division lemma to get

34 = 28 x 1 + 6

We consider the new divisor 28 and the new remainder 6,and apply the division lemma to get

28 = 6 x 4 + 4

We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get

6 = 4 x 1 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 198 and 362 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(28,6) = HCF(34,28) = HCF(164,34) = HCF(198,164) = HCF(362,198) .

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

Step 1: Since 873 > 2, we apply the division lemma to 873 and 2, to get

873 = 2 x 436 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 873 is 1

Notice that 1 = HCF(2,1) = HCF(873,2) .
