HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 796, 641, 291 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 796, 641, 291 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 796, 641, 291 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 796, 641, 291 is 1.

HCF(796, 641, 291) = 1

Highest common factor (HCF) of 796, 641, 291 is 1.

Highest Common Factor of 796,641,291 using Euclid's algorithm

Highest Common Factor of 796,641,291 is 1

Step 1: Since 796 > 641, we apply the division lemma to 796 and 641, to get

796 = 641 x 1 + 155

Step 2: Since the reminder 641 ≠ 0, we apply division lemma to 155 and 641, to get

641 = 155 x 4 + 21

Step 3: We consider the new divisor 155 and the new remainder 21, and apply the division lemma to get

155 = 21 x 7 + 8

We consider the new divisor 21 and the new remainder 8,and apply the division lemma to get

21 = 8 x 2 + 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 796 and 641 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(21,8) = HCF(155,21) = HCF(641,155) = HCF(796,641) .

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

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

291 = 1 x 291 + 0

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

Notice that 1 = HCF(291,1) .
