HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 566, 961, 405 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 566, 961, 405 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 566, 961, 405 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 566, 961, 405 is 1.

HCF(566, 961, 405) = 1

HCF of 566, 961, 405 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 566, 961, 405 is 1.

Highest Common Factor of 566,961,405 using Euclid's algorithm

Highest Common Factor of 566,961,405 is 1

Step 1: Since 961 > 566, we apply the division lemma to 961 and 566, to get

961 = 566 x 1 + 395

Step 2: Since the reminder 566 ≠ 0, we apply division lemma to 395 and 566, to get

566 = 395 x 1 + 171

Step 3: We consider the new divisor 395 and the new remainder 171, and apply the division lemma to get

395 = 171 x 2 + 53

We consider the new divisor 171 and the new remainder 53,and apply the division lemma to get

171 = 53 x 3 + 12

We consider the new divisor 53 and the new remainder 12,and apply the division lemma to get

53 = 12 x 4 + 5

We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get

12 = 5 x 2 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 566 and 961 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(53,12) = HCF(171,53) = HCF(395,171) = HCF(566,395) = HCF(961,566) .

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

Step 1: Since 405 > 1, we apply the division lemma to 405 and 1, to get

405 = 1 x 405 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 405 is 1

Notice that 1 = HCF(405,1) .
