HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 867, 18613 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 867, 18613 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 867, 18613 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 867, 18613 is 1.
HCF(867, 18613) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 867, 18613 is 1.
Step 1: Since 18613 > 867, we apply the division lemma to 18613 and 867, to get
18613 = 867 x 21 + 406
Step 2: Since the reminder 867 ≠ 0, we apply division lemma to 406 and 867, to get
867 = 406 x 2 + 55
Step 3: We consider the new divisor 406 and the new remainder 55, and apply the division lemma to get
406 = 55 x 7 + 21
We consider the new divisor 55 and the new remainder 21,and apply the division lemma to get
55 = 21 x 2 + 13
We consider the new divisor 21 and the new remainder 13,and apply the division lemma to get
21 = 13 x 1 + 8
We consider the new divisor 13 and the new remainder 8,and apply the division lemma to get
13 = 8 x 1 + 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 867 and 18613 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(21,13) = HCF(55,21) = HCF(406,55) = HCF(867,406) = HCF(18613,867) .
Here are some samples of HCF using Euclid's Algorithm calculations.
