HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 486, 652, 818 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 486, 652, 818 is 2 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 486, 652, 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 486, 652, 818 is 2.

HCF(486, 652, 818) = 2

HCF of 486, 652, 818 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 486, 652, 818 is 2.

Highest Common Factor of 486,652,818 using Euclid's algorithm

Highest Common Factor of 486,652,818 is 2

Step 1: Since 652 > 486, we apply the division lemma to 652 and 486, to get

652 = 486 x 1 + 166

Step 2: Since the reminder 486 ≠ 0, we apply division lemma to 166 and 486, to get

486 = 166 x 2 + 154

Step 3: We consider the new divisor 166 and the new remainder 154, and apply the division lemma to get

166 = 154 x 1 + 12

We consider the new divisor 154 and the new remainder 12,and apply the division lemma to get

154 = 12 x 12 + 10

We consider the new divisor 12 and the new remainder 10,and apply the division lemma to get

12 = 10 x 1 + 2

We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get

10 = 2 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 486 and 652 is 2

Notice that 2 = HCF(10,2) = HCF(12,10) = HCF(154,12) = HCF(166,154) = HCF(486,166) = HCF(652,486) .

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

Step 1: Since 818 > 2, we apply the division lemma to 818 and 2, to get

818 = 2 x 409 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 818 is 2

Notice that 2 = HCF(818,2) .
