HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 392, 4309, 6430 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 392, 4309, 6430 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 392, 4309, 6430 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 392, 4309, 6430 is 1.
HCF(392, 4309, 6430) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 392, 4309, 6430 is 1.
Step 1: Since 4309 > 392, we apply the division lemma to 4309 and 392, to get
4309 = 392 x 10 + 389
Step 2: Since the reminder 392 ≠ 0, we apply division lemma to 389 and 392, to get
392 = 389 x 1 + 3
Step 3: We consider the new divisor 389 and the new remainder 3, and apply the division lemma to get
389 = 3 x 129 + 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 392 and 4309 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(389,3) = HCF(392,389) = HCF(4309,392) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 6430 > 1, we apply the division lemma to 6430 and 1, to get
6430 = 1 x 6430 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 6430 is 1
Notice that 1 = HCF(6430,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 392, 4309, 6430?
Answer: HCF of 392, 4309, 6430 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 392, 4309, 6430 using Euclid's Algorithm?
Answer: For arbitrary numbers 392, 4309, 6430 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
