HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 269, 397, 797 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 269, 397, 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 269, 397, 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 269, 397, 797 is 1.

HCF(269, 397, 797) = 1

Highest common factor (HCF) of 269, 397, 797 is 1.

Highest Common Factor of 269,397,797 using Euclid's algorithm

Highest Common Factor of 269,397,797 is 1

Step 1: Since 397 > 269, we apply the division lemma to 397 and 269, to get

397 = 269 x 1 + 128

Step 2: Since the reminder 269 ≠ 0, we apply division lemma to 128 and 269, to get

269 = 128 x 2 + 13

Step 3: We consider the new divisor 128 and the new remainder 13, and apply the division lemma to get

128 = 13 x 9 + 11

We consider the new divisor 13 and the new remainder 11,and apply the division lemma to get

13 = 11 x 1 + 2

We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get

11 = 2 x 5 + 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 269 and 397 is 1

Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(13,11) = HCF(128,13) = HCF(269,128) = HCF(397,269) .

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) .
