HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 818, 948, 660 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 818, 948, 660 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 818, 948, 660 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 818, 948, 660 is 2.

HCF(818, 948, 660) = 2

HCF of 818, 948, 660 using Euclid's algorithm

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

Highest common factor (HCF) of 818, 948, 660 is 2.

Highest Common Factor of 818,948,660 using Euclid's algorithm

Highest Common Factor of 818,948,660 is 2

Step 1: Since 948 > 818, we apply the division lemma to 948 and 818, to get

948 = 818 x 1 + 130

Step 2: Since the reminder 818 ≠ 0, we apply division lemma to 130 and 818, to get

818 = 130 x 6 + 38

Step 3: We consider the new divisor 130 and the new remainder 38, and apply the division lemma to get

130 = 38 x 3 + 16

We consider the new divisor 38 and the new remainder 16,and apply the division lemma to get

38 = 16 x 2 + 6

We consider the new divisor 16 and the new remainder 6,and apply the division lemma to get

16 = 6 x 2 + 4

We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get

6 = 4 x 1 + 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 818 and 948 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(16,6) = HCF(38,16) = HCF(130,38) = HCF(818,130) = HCF(948,818) .

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

Step 1: Since 660 > 2, we apply the division lemma to 660 and 2, to get

660 = 2 x 330 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 660 is 2

Notice that 2 = HCF(660,2) .
