HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7093, 8111, 21733 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 7093, 8111, 21733 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 7093, 8111, 21733 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 7093, 8111, 21733 is 1.
HCF(7093, 8111, 21733) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 7093, 8111, 21733 is 1.
Step 1: Since 8111 > 7093, we apply the division lemma to 8111 and 7093, to get
8111 = 7093 x 1 + 1018
Step 2: Since the reminder 7093 ≠ 0, we apply division lemma to 1018 and 7093, to get
7093 = 1018 x 6 + 985
Step 3: We consider the new divisor 1018 and the new remainder 985, and apply the division lemma to get
1018 = 985 x 1 + 33
We consider the new divisor 985 and the new remainder 33,and apply the division lemma to get
985 = 33 x 29 + 28
We consider the new divisor 33 and the new remainder 28,and apply the division lemma to get
33 = 28 x 1 + 5
We consider the new divisor 28 and the new remainder 5,and apply the division lemma to get
28 = 5 x 5 + 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 7093 and 8111 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(28,5) = HCF(33,28) = HCF(985,33) = HCF(1018,985) = HCF(7093,1018) = HCF(8111,7093) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 21733 > 1, we apply the division lemma to 21733 and 1, to get
21733 = 1 x 21733 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 21733 is 1
Notice that 1 = HCF(21733,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
