HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 461, 855, 820 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 461, 855, 820 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 461, 855, 820 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 461, 855, 820 is 1.

HCF(461, 855, 820) = 1

Highest common factor (HCF) of 461, 855, 820 is 1.

Highest Common Factor of 461,855,820 using Euclid's algorithm

Highest Common Factor of 461,855,820 is 1

Step 1: Since 855 > 461, we apply the division lemma to 855 and 461, to get

855 = 461 x 1 + 394

Step 2: Since the reminder 461 ≠ 0, we apply division lemma to 394 and 461, to get

461 = 394 x 1 + 67

Step 3: We consider the new divisor 394 and the new remainder 67, and apply the division lemma to get

394 = 67 x 5 + 59

We consider the new divisor 67 and the new remainder 59,and apply the division lemma to get

67 = 59 x 1 + 8

We consider the new divisor 59 and the new remainder 8,and apply the division lemma to get

59 = 8 x 7 + 3

We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get

8 = 3 x 2 + 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 461 and 855 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(59,8) = HCF(67,59) = HCF(394,67) = HCF(461,394) = HCF(855,461) .

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

Step 1: Since 820 > 1, we apply the division lemma to 820 and 1, to get

820 = 1 x 820 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 820 is 1

Notice that 1 = HCF(820,1) .
