HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 8181, 7169 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 8181, 7169 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 8181, 7169 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 8181, 7169 is 1.
HCF(8181, 7169) = 1
HCF of 8181, 7169 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 8181, 7169 is 1.
Highest Common Factor of 8181,7169 is 1
Step 1: Since 8181 > 7169, we apply the division lemma to 8181 and 7169, to get
8181 = 7169 x 1 + 1012
Step 2: Since the reminder 7169 ≠ 0, we apply division lemma to 1012 and 7169, to get
7169 = 1012 x 7 + 85
Step 3: We consider the new divisor 1012 and the new remainder 85, and apply the division lemma to get
1012 = 85 x 11 + 77
We consider the new divisor 85 and the new remainder 77,and apply the division lemma to get
85 = 77 x 1 + 8
We consider the new divisor 77 and the new remainder 8,and apply the division lemma to get
77 = 8 x 9 + 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 8181 and 7169 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(77,8) = HCF(85,77) = HCF(1012,85) = HCF(7169,1012) = HCF(8181,7169) .
