HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 57, 95, 303, 797 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 57, 95, 303, 797 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 57, 95, 303, 797 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 57, 95, 303, 797 is 1.

HCF(57, 95, 303, 797) = 1

HCF of 57, 95, 303, 797 using Euclid's algorithm

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

Highest common factor (HCF) of 57, 95, 303, 797 is 1.

Highest Common Factor of 57,95,303,797 using Euclid's algorithm

Highest Common Factor of 57,95,303,797 is 1

Step 1: Since 95 > 57, we apply the division lemma to 95 and 57, to get

95 = 57 x 1 + 38

Step 2: Since the reminder 57 ≠ 0, we apply division lemma to 38 and 57, to get

57 = 38 x 1 + 19

Step 3: We consider the new divisor 38 and the new remainder 19, and apply the division lemma to get

38 = 19 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 19, the HCF of 57 and 95 is 19

Notice that 19 = HCF(38,19) = HCF(57,38) = HCF(95,57) .


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

Step 1: Since 303 > 19, we apply the division lemma to 303 and 19, to get

303 = 19 x 15 + 18

Step 2: Since the reminder 19 ≠ 0, we apply division lemma to 18 and 19, to get

19 = 18 x 1 + 1

Step 3: We consider the new divisor 18 and the new remainder 1, and apply the division lemma to get

18 = 1 x 18 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 19 and 303 is 1

Notice that 1 = HCF(18,1) = HCF(19,18) = HCF(303,19) .


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

Step 1: Since 797 > 1, we apply the division lemma to 797 and 1, to get

797 = 1 x 797 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 797 is 1

Notice that 1 = HCF(797,1) .
