HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 203, 485, 453 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 203, 485, 453 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, 485, 453 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, 485, 453 is 1.

HCF(203, 485, 453) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 203, 485, 453 is 1.

Highest Common Factor of 203,485,453 using Euclid's algorithm

Highest Common Factor of 203,485,453 is 1

Step 1: Since 485 > 203, we apply the division lemma to 485 and 203, to get

485 = 203 x 2 + 79

Step 2: Since the reminder 203 ≠ 0, we apply division lemma to 79 and 203, to get

203 = 79 x 2 + 45

Step 3: We consider the new divisor 79 and the new remainder 45, and apply the division lemma to get

79 = 45 x 1 + 34

We consider the new divisor 45 and the new remainder 34,and apply the division lemma to get

45 = 34 x 1 + 11

We consider the new divisor 34 and the new remainder 11,and apply the division lemma to get

34 = 11 x 3 + 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 203 and 485 is 1

Notice that 1 = HCF(11,1) = HCF(34,11) = HCF(45,34) = HCF(79,45) = HCF(203,79) = HCF(485,203) .

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

Step 1: Since 453 > 1, we apply the division lemma to 453 and 1, to get

453 = 1 x 453 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 453 is 1

Notice that 1 = HCF(453,1) .
