HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 797, 302, 703 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 797, 302, 703 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 797, 302, 703 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 797, 302, 703 is 1.

HCF(797, 302, 703) = 1

Highest common factor (HCF) of 797, 302, 703 is 1.

Highest Common Factor of 797,302,703 using Euclid's algorithm

Highest Common Factor of 797,302,703 is 1

Step 1: Since 797 > 302, we apply the division lemma to 797 and 302, to get

797 = 302 x 2 + 193

Step 2: Since the reminder 302 ≠ 0, we apply division lemma to 193 and 302, to get

302 = 193 x 1 + 109

Step 3: We consider the new divisor 193 and the new remainder 109, and apply the division lemma to get

193 = 109 x 1 + 84

We consider the new divisor 109 and the new remainder 84,and apply the division lemma to get

109 = 84 x 1 + 25

We consider the new divisor 84 and the new remainder 25,and apply the division lemma to get

84 = 25 x 3 + 9

We consider the new divisor 25 and the new remainder 9,and apply the division lemma to get

25 = 9 x 2 + 7

We consider the new divisor 9 and the new remainder 7,and apply the division lemma to get

9 = 7 x 1 + 2

We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get

7 = 2 x 3 + 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 797 and 302 is 1

Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(25,9) = HCF(84,25) = HCF(109,84) = HCF(193,109) = HCF(302,193) = HCF(797,302) .

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

Step 1: Since 703 > 1, we apply the division lemma to 703 and 1, to get

703 = 1 x 703 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 703 is 1

Notice that 1 = HCF(703,1) .
