HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 247, 203, 450 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 247, 203, 450 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 247, 203, 450 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 247, 203, 450 is 1.

HCF(247, 203, 450) = 1

Highest Common Factor of 247,203,450 using Euclid's algorithm

Highest Common Factor of 247,203,450 is 1

Step 1: Since 247 > 203, we apply the division lemma to 247 and 203, to get

247 = 203 x 1 + 44

Step 2: Since the reminder 203 ≠ 0, we apply division lemma to 44 and 203, to get

203 = 44 x 4 + 27

Step 3: We consider the new divisor 44 and the new remainder 27, and apply the division lemma to get

44 = 27 x 1 + 17

We consider the new divisor 27 and the new remainder 17,and apply the division lemma to get

27 = 17 x 1 + 10

We consider the new divisor 17 and the new remainder 10,and apply the division lemma to get

17 = 10 x 1 + 7

We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get

10 = 7 x 1 + 3

We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get

7 = 3 x 2 + 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 247 and 203 is 1

Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(17,10) = HCF(27,17) = HCF(44,27) = HCF(203,44) = HCF(247,203) .


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

Step 1: Since 450 > 1, we apply the division lemma to 450 and 1, to get

450 = 1 x 450 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 450 is 1

Notice that 1 = HCF(450,1) .
