HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 198, 635, 863 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 198, 635, 863 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, 635, 863 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, 635, 863 is 1.

HCF(198, 635, 863) = 1

Highest common factor (HCF) of 198, 635, 863 is 1.

Highest Common Factor of 198,635,863 using Euclid's algorithm

Highest Common Factor of 198,635,863 is 1

Step 1: Since 635 > 198, we apply the division lemma to 635 and 198, to get

635 = 198 x 3 + 41

Step 2: Since the reminder 198 ≠ 0, we apply division lemma to 41 and 198, to get

198 = 41 x 4 + 34

Step 3: We consider the new divisor 41 and the new remainder 34, and apply the division lemma to get

41 = 34 x 1 + 7

We consider the new divisor 34 and the new remainder 7,and apply the division lemma to get

34 = 7 x 4 + 6

We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get

7 = 6 x 1 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 198 and 635 is 1

Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(34,7) = HCF(41,34) = HCF(198,41) = HCF(635,198) .

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

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

863 = 1 x 863 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 863 is 1

Notice that 1 = HCF(863,1) .
