HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 838, 231 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 838, 231 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 838, 231 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 838, 231 is 1.
HCF(838, 231) = 1
HCF of 838, 231 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 838, 231 is 1.
Highest Common Factor of 838,231 is 1
Step 1: Since 838 > 231, we apply the division lemma to 838 and 231, to get
838 = 231 x 3 + 145
Step 2: Since the reminder 231 ≠ 0, we apply division lemma to 145 and 231, to get
231 = 145 x 1 + 86
Step 3: We consider the new divisor 145 and the new remainder 86, and apply the division lemma to get
145 = 86 x 1 + 59
We consider the new divisor 86 and the new remainder 59,and apply the division lemma to get
86 = 59 x 1 + 27
We consider the new divisor 59 and the new remainder 27,and apply the division lemma to get
59 = 27 x 2 + 5
We consider the new divisor 27 and the new remainder 5,and apply the division lemma to get
27 = 5 x 5 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 838 and 231 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(27,5) = HCF(59,27) = HCF(86,59) = HCF(145,86) = HCF(231,145) = HCF(838,231) .
