HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 86, 398 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 86, 398 is 2 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 86, 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 86, 398 is 2.
HCF(86, 398) = 2
HCF of 86, 398 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 86, 398 is 2.
Highest Common Factor of 86,398 is 2
Step 1: Since 398 > 86, we apply the division lemma to 398 and 86, to get
398 = 86 x 4 + 54
Step 2: Since the reminder 86 ≠ 0, we apply division lemma to 54 and 86, to get
86 = 54 x 1 + 32
Step 3: We consider the new divisor 54 and the new remainder 32, and apply the division lemma to get
54 = 32 x 1 + 22
We consider the new divisor 32 and the new remainder 22,and apply the division lemma to get
32 = 22 x 1 + 10
We consider the new divisor 22 and the new remainder 10,and apply the division lemma to get
22 = 10 x 2 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 86 and 398 is 2
Notice that 2 = HCF(10,2) = HCF(22,10) = HCF(32,22) = HCF(54,32) = HCF(86,54) = HCF(398,86) .
