HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 165, 386 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 165, 386 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 165, 386 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 165, 386 is 1.
HCF(165, 386) = 1
HCF of 165, 386 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 165, 386 is 1.
Highest Common Factor of 165,386 is 1
Step 1: Since 386 > 165, we apply the division lemma to 386 and 165, to get
386 = 165 x 2 + 56
Step 2: Since the reminder 165 ≠ 0, we apply division lemma to 56 and 165, to get
165 = 56 x 2 + 53
Step 3: We consider the new divisor 56 and the new remainder 53, and apply the division lemma to get
56 = 53 x 1 + 3
We consider the new divisor 53 and the new remainder 3,and apply the division lemma to get
53 = 3 x 17 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 165 and 386 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(53,3) = HCF(56,53) = HCF(165,56) = HCF(386,165) .
