HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 303, 485, 247 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 303, 485, 247 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 303, 485, 247 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 303, 485, 247 is 1.

HCF(303, 485, 247) = 1

HCF of 303, 485, 247 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 303, 485, 247 is 1.

Highest Common Factor of 303,485,247 using Euclid's algorithm

Highest Common Factor of 303,485,247 is 1

Step 1: Since 485 > 303, we apply the division lemma to 485 and 303, to get

485 = 303 x 1 + 182

Step 2: Since the reminder 303 ≠ 0, we apply division lemma to 182 and 303, to get

303 = 182 x 1 + 121

Step 3: We consider the new divisor 182 and the new remainder 121, and apply the division lemma to get

182 = 121 x 1 + 61

We consider the new divisor 121 and the new remainder 61,and apply the division lemma to get

121 = 61 x 1 + 60

We consider the new divisor 61 and the new remainder 60,and apply the division lemma to get

61 = 60 x 1 + 1

We consider the new divisor 60 and the new remainder 1,and apply the division lemma to get

60 = 1 x 60 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 303 and 485 is 1

Notice that 1 = HCF(60,1) = HCF(61,60) = HCF(121,61) = HCF(182,121) = HCF(303,182) = HCF(485,303) .

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

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

247 = 1 x 247 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 247 is 1

Notice that 1 = HCF(247,1) .
