HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 206, 957, 897 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 206, 957, 897 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 206, 957, 897 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 206, 957, 897 is 1.

HCF(206, 957, 897) = 1

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

HCF of:

Highest common factor (HCF) of 206, 957, 897 is 1.

Highest Common Factor of 206,957,897 using Euclid's algorithm

Highest Common Factor of 206,957,897 is 1

Step 1: Since 957 > 206, we apply the division lemma to 957 and 206, to get

957 = 206 x 4 + 133

Step 2: Since the reminder 206 ≠ 0, we apply division lemma to 133 and 206, to get

206 = 133 x 1 + 73

Step 3: We consider the new divisor 133 and the new remainder 73, and apply the division lemma to get

133 = 73 x 1 + 60

We consider the new divisor 73 and the new remainder 60,and apply the division lemma to get

73 = 60 x 1 + 13

We consider the new divisor 60 and the new remainder 13,and apply the division lemma to get

60 = 13 x 4 + 8

We consider the new divisor 13 and the new remainder 8,and apply the division lemma to get

13 = 8 x 1 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

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 206 and 957 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(60,13) = HCF(73,60) = HCF(133,73) = HCF(206,133) = HCF(957,206) .

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

Step 1: Since 897 > 1, we apply the division lemma to 897 and 1, to get

897 = 1 x 897 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 897 is 1

Notice that 1 = HCF(897,1) .
