HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 399, 9929 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 399, 9929 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 399, 9929 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 399, 9929 is 1.

HCF(399, 9929) = 1

HCF of 399, 9929 using Euclid's algorithm

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

Highest common factor (HCF) of 399, 9929 is 1.

Highest Common Factor of 399,9929 using Euclid's algorithm

Highest Common Factor of 399,9929 is 1

Step 1: Since 9929 > 399, we apply the division lemma to 9929 and 399, to get

9929 = 399 x 24 + 353

Step 2: Since the reminder 399 ≠ 0, we apply division lemma to 353 and 399, to get

399 = 353 x 1 + 46

Step 3: We consider the new divisor 353 and the new remainder 46, and apply the division lemma to get

353 = 46 x 7 + 31

We consider the new divisor 46 and the new remainder 31,and apply the division lemma to get

46 = 31 x 1 + 15

We consider the new divisor 31 and the new remainder 15,and apply the division lemma to get

31 = 15 x 2 + 1

We consider the new divisor 15 and the new remainder 1,and apply the division lemma to get

15 = 1 x 15 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 399 and 9929 is 1

Notice that 1 = HCF(15,1) = HCF(31,15) = HCF(46,31) = HCF(353,46) = HCF(399,353) = HCF(9929,399) .
