HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 801, 822, 363 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 801, 822, 363 is 3 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 801, 822, 363 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 801, 822, 363 is 3.

HCF(801, 822, 363) = 3

HCF of 801, 822, 363 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 801, 822, 363 is 3.

Highest Common Factor of 801,822,363 using Euclid's algorithm

Highest Common Factor of 801,822,363 is 3

Step 1: Since 822 > 801, we apply the division lemma to 822 and 801, to get

822 = 801 x 1 + 21

Step 2: Since the reminder 801 ≠ 0, we apply division lemma to 21 and 801, to get

801 = 21 x 38 + 3

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

21 = 3 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 801 and 822 is 3

Notice that 3 = HCF(21,3) = HCF(801,21) = HCF(822,801) .


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

Step 1: Since 363 > 3, we apply the division lemma to 363 and 3, to get

363 = 3 x 121 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 363 is 3

Notice that 3 = HCF(363,3) .
