HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 470, 252, 797 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 470, 252, 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 470, 252, 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 470, 252, 797 is 1.

HCF(470, 252, 797) = 1

Highest common factor (HCF) of 470, 252, 797 is 1.

Highest Common Factor of 470,252,797 using Euclid's algorithm

Highest Common Factor of 470,252,797 is 1

Step 1: Since 470 > 252, we apply the division lemma to 470 and 252, to get

470 = 252 x 1 + 218

Step 2: Since the reminder 252 ≠ 0, we apply division lemma to 218 and 252, to get

252 = 218 x 1 + 34

Step 3: We consider the new divisor 218 and the new remainder 34, and apply the division lemma to get

218 = 34 x 6 + 14

We consider the new divisor 34 and the new remainder 14,and apply the division lemma to get

34 = 14 x 2 + 6

We consider the new divisor 14 and the new remainder 6,and apply the division lemma to get

14 = 6 x 2 + 2

We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get

6 = 2 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 470 and 252 is 2

Notice that 2 = HCF(6,2) = HCF(14,6) = HCF(34,14) = HCF(218,34) = HCF(252,218) = HCF(470,252) .

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

Step 1: Since 797 > 2, we apply the division lemma to 797 and 2, to get

797 = 2 x 398 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 797 is 1

Notice that 1 = HCF(2,1) = HCF(797,2) .
