HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 445, 808, 449 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 445, 808, 449 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 445, 808, 449 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 445, 808, 449 is 1.

HCF(445, 808, 449) = 1

Highest common factor (HCF) of 445, 808, 449 is 1.

Highest Common Factor of 445,808,449 using Euclid's algorithm

Highest Common Factor of 445,808,449 is 1

Step 1: Since 808 > 445, we apply the division lemma to 808 and 445, to get

808 = 445 x 1 + 363

Step 2: Since the reminder 445 ≠ 0, we apply division lemma to 363 and 445, to get

445 = 363 x 1 + 82

Step 3: We consider the new divisor 363 and the new remainder 82, and apply the division lemma to get

363 = 82 x 4 + 35

We consider the new divisor 82 and the new remainder 35,and apply the division lemma to get

82 = 35 x 2 + 12

We consider the new divisor 35 and the new remainder 12,and apply the division lemma to get

35 = 12 x 2 + 11

We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get

12 = 11 x 1 + 1

We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get

11 = 1 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 445 and 808 is 1

Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(35,12) = HCF(82,35) = HCF(363,82) = HCF(445,363) = HCF(808,445) .

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

Step 1: Since 449 > 1, we apply the division lemma to 449 and 1, to get

449 = 1 x 449 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 449 is 1

Notice that 1 = HCF(449,1) .
