HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 758, 389 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 758, 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 758, 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 758, 389 is 1.
HCF(758, 389) = 1
HCF of 758, 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 758, 389 is 1.
Highest Common Factor of 758,389 is 1
Step 1: Since 758 > 389, we apply the division lemma to 758 and 389, to get
758 = 389 x 1 + 369
Step 2: Since the reminder 389 ≠ 0, we apply division lemma to 369 and 389, to get
389 = 369 x 1 + 20
Step 3: We consider the new divisor 369 and the new remainder 20, and apply the division lemma to get
369 = 20 x 18 + 9
We consider the new divisor 20 and the new remainder 9,and apply the division lemma to get
20 = 9 x 2 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 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 758 and 389 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(20,9) = HCF(369,20) = HCF(389,369) = HCF(758,389) .
