HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 873, 605, 814 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 873, 605, 814 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 873, 605, 814 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 873, 605, 814 is 1.
HCF(873, 605, 814) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 873, 605, 814 is 1.
Step 1: Since 873 > 605, we apply the division lemma to 873 and 605, to get
873 = 605 x 1 + 268
Step 2: Since the reminder 605 ≠ 0, we apply division lemma to 268 and 605, to get
605 = 268 x 2 + 69
Step 3: We consider the new divisor 268 and the new remainder 69, and apply the division lemma to get
268 = 69 x 3 + 61
We consider the new divisor 69 and the new remainder 61,and apply the division lemma to get
69 = 61 x 1 + 8
We consider the new divisor 61 and the new remainder 8,and apply the division lemma to get
61 = 8 x 7 + 5
We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get
8 = 5 x 1 + 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 873 and 605 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(61,8) = HCF(69,61) = HCF(268,69) = HCF(605,268) = HCF(873,605) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 814 > 1, we apply the division lemma to 814 and 1, to get
814 = 1 x 814 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 814 is 1
Notice that 1 = HCF(814,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
