HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 449, 218, 619 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 449, 218, 619 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 449, 218, 619 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 449, 218, 619 is 1.

HCF(449, 218, 619) = 1

HCF of 449, 218, 619 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 449, 218, 619 is 1.

Highest Common Factor of 449,218,619 using Euclid's algorithm

Highest Common Factor of 449,218,619 is 1

Step 1: Since 449 > 218, we apply the division lemma to 449 and 218, to get

449 = 218 x 2 + 13

Step 2: Since the reminder 218 ≠ 0, we apply division lemma to 13 and 218, to get

218 = 13 x 16 + 10

Step 3: We consider the new divisor 13 and the new remainder 10, and apply the division lemma to get

13 = 10 x 1 + 3

We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get

10 = 3 x 3 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 449 and 218 is 1

Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(13,10) = HCF(218,13) = HCF(449,218) .

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

Step 1: Since 619 > 1, we apply the division lemma to 619 and 1, to get

619 = 1 x 619 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 619 is 1

Notice that 1 = HCF(619,1) .
