HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 203, 419 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 203, 419 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 203, 419 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 203, 419 is 1.

HCF(203, 419) = 1

Highest common factor (HCF) of 203, 419 is 1.

Highest Common Factor of 203,419 using Euclid's algorithm

Highest Common Factor of 203,419 is 1

Step 1: Since 419 > 203, we apply the division lemma to 419 and 203, to get

419 = 203 x 2 + 13

Step 2: Since the reminder 203 ≠ 0, we apply division lemma to 13 and 203, to get

203 = 13 x 15 + 8

Step 3: We consider the new divisor 13 and the new remainder 8, and apply the division lemma to get

13 = 8 x 1 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 203 and 419 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(203,13) = HCF(419,203) .
