HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 629, 820, 818 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 629, 820, 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 629, 820, 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 629, 820, 818 is 1.

HCF(629, 820, 818) = 1

Highest common factor (HCF) of 629, 820, 818 is 1.

Highest Common Factor of 629,820,818 using Euclid's algorithm

Highest Common Factor of 629,820,818 is 1

Step 1: Since 820 > 629, we apply the division lemma to 820 and 629, to get

820 = 629 x 1 + 191

Step 2: Since the reminder 629 ≠ 0, we apply division lemma to 191 and 629, to get

629 = 191 x 3 + 56

Step 3: We consider the new divisor 191 and the new remainder 56, and apply the division lemma to get

191 = 56 x 3 + 23

We consider the new divisor 56 and the new remainder 23,and apply the division lemma to get

56 = 23 x 2 + 10

We consider the new divisor 23 and the new remainder 10,and apply the division lemma to get

23 = 10 x 2 + 3

We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get

10 = 3 x 3 + 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 629 and 820 is 1

Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(23,10) = HCF(56,23) = HCF(191,56) = HCF(629,191) = HCF(820,629) .

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) .
