HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 323, 2419, 9728 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 323, 2419, 9728 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 323, 2419, 9728 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 323, 2419, 9728 is 1.
HCF(323, 2419, 9728) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 323, 2419, 9728 is 1.
Step 1: Since 2419 > 323, we apply the division lemma to 2419 and 323, to get
2419 = 323 x 7 + 158
Step 2: Since the reminder 323 ≠ 0, we apply division lemma to 158 and 323, to get
323 = 158 x 2 + 7
Step 3: We consider the new divisor 158 and the new remainder 7, and apply the division lemma to get
158 = 7 x 22 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 323 and 2419 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(158,7) = HCF(323,158) = HCF(2419,323) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 9728 > 1, we apply the division lemma to 9728 and 1, to get
9728 = 1 x 9728 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 9728 is 1
Notice that 1 = HCF(9728,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
