HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 812, 330, 509 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 812, 330, 509 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 812, 330, 509 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 812, 330, 509 is 1.

HCF(812, 330, 509) = 1

Highest common factor (HCF) of 812, 330, 509 is 1.

Highest Common Factor of 812,330,509 using Euclid's algorithm

Highest Common Factor of 812,330,509 is 1

Step 1: Since 812 > 330, we apply the division lemma to 812 and 330, to get

812 = 330 x 2 + 152

Step 2: Since the reminder 330 ≠ 0, we apply division lemma to 152 and 330, to get

330 = 152 x 2 + 26

Step 3: We consider the new divisor 152 and the new remainder 26, and apply the division lemma to get

152 = 26 x 5 + 22

We consider the new divisor 26 and the new remainder 22,and apply the division lemma to get

26 = 22 x 1 + 4

We consider the new divisor 22 and the new remainder 4,and apply the division lemma to get

22 = 4 x 5 + 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 812 and 330 is 2

Notice that 2 = HCF(4,2) = HCF(22,4) = HCF(26,22) = HCF(152,26) = HCF(330,152) = HCF(812,330) .

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

Step 1: Since 509 > 2, we apply the division lemma to 509 and 2, to get

509 = 2 x 254 + 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 509 is 1

Notice that 1 = HCF(2,1) = HCF(509,2) .
