HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 318, 821, 566 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 318, 821, 566 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 318, 821, 566 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 318, 821, 566 is 1.

HCF(318, 821, 566) = 1

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

HCF of:

Highest common factor (HCF) of 318, 821, 566 is 1.

Highest Common Factor of 318,821,566 using Euclid's algorithm

Highest Common Factor of 318,821,566 is 1

Step 1: Since 821 > 318, we apply the division lemma to 821 and 318, to get

821 = 318 x 2 + 185

Step 2: Since the reminder 318 ≠ 0, we apply division lemma to 185 and 318, to get

318 = 185 x 1 + 133

Step 3: We consider the new divisor 185 and the new remainder 133, and apply the division lemma to get

185 = 133 x 1 + 52

We consider the new divisor 133 and the new remainder 52,and apply the division lemma to get

133 = 52 x 2 + 29

We consider the new divisor 52 and the new remainder 29,and apply the division lemma to get

52 = 29 x 1 + 23

We consider the new divisor 29 and the new remainder 23,and apply the division lemma to get

29 = 23 x 1 + 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 318 and 821 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(23,6) = HCF(29,23) = HCF(52,29) = HCF(133,52) = HCF(185,133) = HCF(318,185) = HCF(821,318) .

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

Step 1: Since 566 > 1, we apply the division lemma to 566 and 1, to get

566 = 1 x 566 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 566 is 1

Notice that 1 = HCF(566,1) .
