HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 406, 855, 808 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 406, 855, 808 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 406, 855, 808 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 406, 855, 808 is 1.

HCF(406, 855, 808) = 1

Highest common factor (HCF) of 406, 855, 808 is 1.

Highest Common Factor of 406,855,808 using Euclid's algorithm

Highest Common Factor of 406,855,808 is 1

Step 1: Since 855 > 406, we apply the division lemma to 855 and 406, to get

855 = 406 x 2 + 43

Step 2: Since the reminder 406 ≠ 0, we apply division lemma to 43 and 406, to get

406 = 43 x 9 + 19

Step 3: We consider the new divisor 43 and the new remainder 19, and apply the division lemma to get

43 = 19 x 2 + 5

We consider the new divisor 19 and the new remainder 5,and apply the division lemma to get

19 = 5 x 3 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 406 and 855 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(19,5) = HCF(43,19) = HCF(406,43) = HCF(855,406) .

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

Step 1: Since 808 > 1, we apply the division lemma to 808 and 1, to get

808 = 1 x 808 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 808 is 1

Notice that 1 = HCF(808,1) .
