HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 404, 791, 822 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 404, 791, 822 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 404, 791, 822 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 404, 791, 822 is 1.

HCF(404, 791, 822) = 1

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

HCF of:

Highest common factor (HCF) of 404, 791, 822 is 1.

Highest Common Factor of 404,791,822 using Euclid's algorithm

Highest Common Factor of 404,791,822 is 1

Step 1: Since 791 > 404, we apply the division lemma to 791 and 404, to get

791 = 404 x 1 + 387

Step 2: Since the reminder 404 ≠ 0, we apply division lemma to 387 and 404, to get

404 = 387 x 1 + 17

Step 3: We consider the new divisor 387 and the new remainder 17, and apply the division lemma to get

387 = 17 x 22 + 13

We consider the new divisor 17 and the new remainder 13,and apply the division lemma to get

17 = 13 x 1 + 4

We consider the new divisor 13 and the new remainder 4,and apply the division lemma to get

13 = 4 x 3 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 404 and 791 is 1

Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(17,13) = HCF(387,17) = HCF(404,387) = HCF(791,404) .


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

Step 1: Since 822 > 1, we apply the division lemma to 822 and 1, to get

822 = 1 x 822 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 822 is 1

Notice that 1 = HCF(822,1) .
