HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 323, 836, 398 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 323, 836, 398 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 323, 836, 398 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 323, 836, 398 is 1.

HCF(323, 836, 398) = 1

Highest common factor (HCF) of 323, 836, 398 is 1.

Highest Common Factor of 323,836,398 using Euclid's algorithm

Highest Common Factor of 323,836,398 is 1

Step 1: Since 836 > 323, we apply the division lemma to 836 and 323, to get

836 = 323 x 2 + 190

Step 2: Since the reminder 323 ≠ 0, we apply division lemma to 190 and 323, to get

323 = 190 x 1 + 133

Step 3: We consider the new divisor 190 and the new remainder 133, and apply the division lemma to get

190 = 133 x 1 + 57

We consider the new divisor 133 and the new remainder 57,and apply the division lemma to get

133 = 57 x 2 + 19

We consider the new divisor 57 and the new remainder 19,and apply the division lemma to get

57 = 19 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 19, the HCF of 323 and 836 is 19

Notice that 19 = HCF(57,19) = HCF(133,57) = HCF(190,133) = HCF(323,190) = HCF(836,323) .

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

Step 1: Since 398 > 19, we apply the division lemma to 398 and 19, to get

398 = 19 x 20 + 18

Step 2: Since the reminder 19 ≠ 0, we apply division lemma to 18 and 19, to get

19 = 18 x 1 + 1

Step 3: We consider the new divisor 18 and the new remainder 1, and apply the division lemma to get

18 = 1 x 18 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 19 and 398 is 1

Notice that 1 = HCF(18,1) = HCF(19,18) = HCF(398,19) .
