HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 265, 570, 268 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 265, 570, 268 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 265, 570, 268 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 265, 570, 268 is 1.

HCF(265, 570, 268) = 1

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

HCF of:

Highest common factor (HCF) of 265, 570, 268 is 1.

Highest Common Factor of 265,570,268 using Euclid's algorithm

Highest Common Factor of 265,570,268 is 1

Step 1: Since 570 > 265, we apply the division lemma to 570 and 265, to get

570 = 265 x 2 + 40

Step 2: Since the reminder 265 ≠ 0, we apply division lemma to 40 and 265, to get

265 = 40 x 6 + 25

Step 3: We consider the new divisor 40 and the new remainder 25, and apply the division lemma to get

40 = 25 x 1 + 15

We consider the new divisor 25 and the new remainder 15,and apply the division lemma to get

25 = 15 x 1 + 10

We consider the new divisor 15 and the new remainder 10,and apply the division lemma to get

15 = 10 x 1 + 5

We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get

10 = 5 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 265 and 570 is 5

Notice that 5 = HCF(10,5) = HCF(15,10) = HCF(25,15) = HCF(40,25) = HCF(265,40) = HCF(570,265) .

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

Step 1: Since 268 > 5, we apply the division lemma to 268 and 5, to get

268 = 5 x 53 + 3

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get

5 = 3 x 1 + 2

Step 3: We consider the new divisor 3 and the new remainder 2, and apply the division lemma to get

3 = 2 x 1 + 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 5 and 268 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(268,5) .
