HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 434, 113, 389 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 434, 113, 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 434, 113, 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 434, 113, 389 is 1.
HCF(434, 113, 389) = 1
HCF of 434, 113, 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 434, 113, 389 is 1.
Highest Common Factor of 434,113,389 is 1
Step 1: Since 434 > 113, we apply the division lemma to 434 and 113, to get
434 = 113 x 3 + 95
Step 2: Since the reminder 113 ≠ 0, we apply division lemma to 95 and 113, to get
113 = 95 x 1 + 18
Step 3: We consider the new divisor 95 and the new remainder 18, and apply the division lemma to get
95 = 18 x 5 + 5
We consider the new divisor 18 and the new remainder 5,and apply the division lemma to get
18 = 5 x 3 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 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 434 and 113 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(18,5) = HCF(95,18) = HCF(113,95) = HCF(434,113) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 389 > 1, we apply the division lemma to 389 and 1, to get
389 = 1 x 389 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 389 is 1
Notice that 1 = HCF(389,1) .
