HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 291, 206, 856 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 291, 206, 856 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 291, 206, 856 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 291, 206, 856 is 1.

HCF(291, 206, 856) = 1

Highest common factor (HCF) of 291, 206, 856 is 1.

Highest Common Factor of 291,206,856 using Euclid's algorithm

Highest Common Factor of 291,206,856 is 1

Step 1: Since 291 > 206, we apply the division lemma to 291 and 206, to get

291 = 206 x 1 + 85

Step 2: Since the reminder 206 ≠ 0, we apply division lemma to 85 and 206, to get

206 = 85 x 2 + 36

Step 3: We consider the new divisor 85 and the new remainder 36, and apply the division lemma to get

85 = 36 x 2 + 13

We consider the new divisor 36 and the new remainder 13,and apply the division lemma to get

36 = 13 x 2 + 10

We consider the new divisor 13 and the new remainder 10,and apply the division lemma to get

13 = 10 x 1 + 3

We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get

10 = 3 x 3 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 291 and 206 is 1

Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(13,10) = HCF(36,13) = HCF(85,36) = HCF(206,85) = HCF(291,206) .

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

Step 1: Since 856 > 1, we apply the division lemma to 856 and 1, to get

856 = 1 x 856 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 856 is 1

Notice that 1 = HCF(856,1) .
