HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 848, 695, 821 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 848, 695, 821 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 848, 695, 821 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 848, 695, 821 is 1.

HCF(848, 695, 821) = 1

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

HCF of:

Highest common factor (HCF) of 848, 695, 821 is 1.

Highest Common Factor of 848,695,821 using Euclid's algorithm

Highest Common Factor of 848,695,821 is 1

Step 1: Since 848 > 695, we apply the division lemma to 848 and 695, to get

848 = 695 x 1 + 153

Step 2: Since the reminder 695 ≠ 0, we apply division lemma to 153 and 695, to get

695 = 153 x 4 + 83

Step 3: We consider the new divisor 153 and the new remainder 83, and apply the division lemma to get

153 = 83 x 1 + 70

We consider the new divisor 83 and the new remainder 70,and apply the division lemma to get

83 = 70 x 1 + 13

We consider the new divisor 70 and the new remainder 13,and apply the division lemma to get

70 = 13 x 5 + 5

We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get

13 = 5 x 2 + 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 848 and 695 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(70,13) = HCF(83,70) = HCF(153,83) = HCF(695,153) = HCF(848,695) .

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

Step 1: Since 821 > 1, we apply the division lemma to 821 and 1, to get

821 = 1 x 821 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 821 is 1

Notice that 1 = HCF(821,1) .
