HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 398, 233 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 398, 233 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 398, 233 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 398, 233 is 1.
HCF(398, 233) = 1
HCF of 398, 233 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 398, 233 is 1.
Highest Common Factor of 398,233 is 1
Step 1: Since 398 > 233, we apply the division lemma to 398 and 233, to get
398 = 233 x 1 + 165
Step 2: Since the reminder 233 ≠ 0, we apply division lemma to 165 and 233, to get
233 = 165 x 1 + 68
Step 3: We consider the new divisor 165 and the new remainder 68, and apply the division lemma to get
165 = 68 x 2 + 29
We consider the new divisor 68 and the new remainder 29,and apply the division lemma to get
68 = 29 x 2 + 10
We consider the new divisor 29 and the new remainder 10,and apply the division lemma to get
29 = 10 x 2 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 398 and 233 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(29,10) = HCF(68,29) = HCF(165,68) = HCF(233,165) = HCF(398,233) .
