HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 8820, 1143 i.e. 9 the largest integer that leaves a remainder zero for all numbers.
HCF of 8820, 1143 is 9 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 8820, 1143 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 8820, 1143 is 9.
HCF(8820, 1143) = 9
HCF of 8820, 1143 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 8820, 1143 is 9.
Highest Common Factor of 8820,1143 is 9
Step 1: Since 8820 > 1143, we apply the division lemma to 8820 and 1143, to get
8820 = 1143 x 7 + 819
Step 2: Since the reminder 1143 ≠ 0, we apply division lemma to 819 and 1143, to get
1143 = 819 x 1 + 324
Step 3: We consider the new divisor 819 and the new remainder 324, and apply the division lemma to get
819 = 324 x 2 + 171
We consider the new divisor 324 and the new remainder 171,and apply the division lemma to get
324 = 171 x 1 + 153
We consider the new divisor 171 and the new remainder 153,and apply the division lemma to get
171 = 153 x 1 + 18
We consider the new divisor 153 and the new remainder 18,and apply the division lemma to get
153 = 18 x 8 + 9
We consider the new divisor 18 and the new remainder 9,and apply the division lemma to get
18 = 9 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 8820 and 1143 is 9
Notice that 9 = HCF(18,9) = HCF(153,18) = HCF(171,153) = HCF(324,171) = HCF(819,324) = HCF(1143,819) = HCF(8820,1143) .
