HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 608, 843, 818 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 608, 843, 818 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 608, 843, 818 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 608, 843, 818 is 1.

HCF(608, 843, 818) = 1

Highest common factor (HCF) of 608, 843, 818 is 1.

Highest Common Factor of 608,843,818 using Euclid's algorithm

Highest Common Factor of 608,843,818 is 1

Step 1: Since 843 > 608, we apply the division lemma to 843 and 608, to get

843 = 608 x 1 + 235

Step 2: Since the reminder 608 ≠ 0, we apply division lemma to 235 and 608, to get

608 = 235 x 2 + 138

Step 3: We consider the new divisor 235 and the new remainder 138, and apply the division lemma to get

235 = 138 x 1 + 97

We consider the new divisor 138 and the new remainder 97,and apply the division lemma to get

138 = 97 x 1 + 41

We consider the new divisor 97 and the new remainder 41,and apply the division lemma to get

97 = 41 x 2 + 15

We consider the new divisor 41 and the new remainder 15,and apply the division lemma to get

41 = 15 x 2 + 11

We consider the new divisor 15 and the new remainder 11,and apply the division lemma to get

15 = 11 x 1 + 4

We consider the new divisor 11 and the new remainder 4,and apply the division lemma to get

11 = 4 x 2 + 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 608 and 843 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(15,11) = HCF(41,15) = HCF(97,41) = HCF(138,97) = HCF(235,138) = HCF(608,235) = HCF(843,608) .

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

Step 1: Since 818 > 1, we apply the division lemma to 818 and 1, to get

818 = 1 x 818 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 818 is 1

Notice that 1 = HCF(818,1) .
