HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 485, 306, 817 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 485, 306, 817 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 485, 306, 817 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 485, 306, 817 is 1.

HCF(485, 306, 817) = 1

Highest common factor (HCF) of 485, 306, 817 is 1.

Highest Common Factor of 485,306,817 using Euclid's algorithm

Highest Common Factor of 485,306,817 is 1

Step 1: Since 485 > 306, we apply the division lemma to 485 and 306, to get

485 = 306 x 1 + 179

Step 2: Since the reminder 306 ≠ 0, we apply division lemma to 179 and 306, to get

306 = 179 x 1 + 127

Step 3: We consider the new divisor 179 and the new remainder 127, and apply the division lemma to get

179 = 127 x 1 + 52

We consider the new divisor 127 and the new remainder 52,and apply the division lemma to get

127 = 52 x 2 + 23

We consider the new divisor 52 and the new remainder 23,and apply the division lemma to get

52 = 23 x 2 + 6

We consider the new divisor 23 and the new remainder 6,and apply the division lemma to get

23 = 6 x 3 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 485 and 306 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(23,6) = HCF(52,23) = HCF(127,52) = HCF(179,127) = HCF(306,179) = HCF(485,306) .

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

Step 1: Since 817 > 1, we apply the division lemma to 817 and 1, to get

817 = 1 x 817 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 817 is 1

Notice that 1 = HCF(817,1) .
