HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 231, 6399 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 231, 6399 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 231, 6399 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 231, 6399 is 3.
HCF(231, 6399) = 3
HCF of 231, 6399 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 231, 6399 is 3.
Highest Common Factor of 231,6399 is 3
Step 1: Since 6399 > 231, we apply the division lemma to 6399 and 231, to get
6399 = 231 x 27 + 162
Step 2: Since the reminder 231 ≠ 0, we apply division lemma to 162 and 231, to get
231 = 162 x 1 + 69
Step 3: We consider the new divisor 162 and the new remainder 69, and apply the division lemma to get
162 = 69 x 2 + 24
We consider the new divisor 69 and the new remainder 24,and apply the division lemma to get
69 = 24 x 2 + 21
We consider the new divisor 24 and the new remainder 21,and apply the division lemma to get
24 = 21 x 1 + 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 231 and 6399 is 3
Notice that 3 = HCF(21,3) = HCF(24,21) = HCF(69,24) = HCF(162,69) = HCF(231,162) = HCF(6399,231) .
