HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 135, 389 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 135, 389 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 135, 389 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 135, 389 is 1.
HCF(135, 389) = 1
HCF of 135, 389 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 135, 389 is 1.
Highest Common Factor of 135,389 is 1
Step 1: Since 389 > 135, we apply the division lemma to 389 and 135, to get
389 = 135 x 2 + 119
Step 2: Since the reminder 135 ≠ 0, we apply division lemma to 119 and 135, to get
135 = 119 x 1 + 16
Step 3: We consider the new divisor 119 and the new remainder 16, and apply the division lemma to get
119 = 16 x 7 + 7
We consider the new divisor 16 and the new remainder 7,and apply the division lemma to get
16 = 7 x 2 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 135 and 389 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(16,7) = HCF(119,16) = HCF(135,119) = HCF(389,135) .
