HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 3468, 1849, 69115 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 3468, 1849, 69115 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 3468, 1849, 69115 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 3468, 1849, 69115 is 1.
HCF(3468, 1849, 69115) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 3468, 1849, 69115 is 1.
Step 1: Since 3468 > 1849, we apply the division lemma to 3468 and 1849, to get
3468 = 1849 x 1 + 1619
Step 2: Since the reminder 1849 ≠ 0, we apply division lemma to 1619 and 1849, to get
1849 = 1619 x 1 + 230
Step 3: We consider the new divisor 1619 and the new remainder 230, and apply the division lemma to get
1619 = 230 x 7 + 9
We consider the new divisor 230 and the new remainder 9,and apply the division lemma to get
230 = 9 x 25 + 5
We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get
9 = 5 x 1 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3468 and 1849 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(230,9) = HCF(1619,230) = HCF(1849,1619) = HCF(3468,1849) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 69115 > 1, we apply the division lemma to 69115 and 1, to get
69115 = 1 x 69115 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 69115 is 1
Notice that 1 = HCF(69115,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
