HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 626, 812, 73 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 626, 812, 73 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 626, 812, 73 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 626, 812, 73 is 1.

HCF(626, 812, 73) = 1

Highest common factor (HCF) of 626, 812, 73 is 1.

Highest Common Factor of 626,812,73 using Euclid's algorithm

Highest Common Factor of 626,812,73 is 1

Step 1: Since 812 > 626, we apply the division lemma to 812 and 626, to get

812 = 626 x 1 + 186

Step 2: Since the reminder 626 ≠ 0, we apply division lemma to 186 and 626, to get

626 = 186 x 3 + 68

Step 3: We consider the new divisor 186 and the new remainder 68, and apply the division lemma to get

186 = 68 x 2 + 50

We consider the new divisor 68 and the new remainder 50,and apply the division lemma to get

68 = 50 x 1 + 18

We consider the new divisor 50 and the new remainder 18,and apply the division lemma to get

50 = 18 x 2 + 14

We consider the new divisor 18 and the new remainder 14,and apply the division lemma to get

18 = 14 x 1 + 4

We consider the new divisor 14 and the new remainder 4,and apply the division lemma to get

14 = 4 x 3 + 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 626 and 812 is 2

Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(18,14) = HCF(50,18) = HCF(68,50) = HCF(186,68) = HCF(626,186) = HCF(812,626) .

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

Step 1: Since 73 > 2, we apply the division lemma to 73 and 2, to get

73 = 2 x 36 + 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 73 is 1

Notice that 1 = HCF(2,1) = HCF(73,2) .
