HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 8143, 7217, 47333 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 8143, 7217, 47333 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 8143, 7217, 47333 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 8143, 7217, 47333 is 1.
HCF(8143, 7217, 47333) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 8143, 7217, 47333 is 1.
Step 1: Since 8143 > 7217, we apply the division lemma to 8143 and 7217, to get
8143 = 7217 x 1 + 926
Step 2: Since the reminder 7217 ≠ 0, we apply division lemma to 926 and 7217, to get
7217 = 926 x 7 + 735
Step 3: We consider the new divisor 926 and the new remainder 735, and apply the division lemma to get
926 = 735 x 1 + 191
We consider the new divisor 735 and the new remainder 191,and apply the division lemma to get
735 = 191 x 3 + 162
We consider the new divisor 191 and the new remainder 162,and apply the division lemma to get
191 = 162 x 1 + 29
We consider the new divisor 162 and the new remainder 29,and apply the division lemma to get
162 = 29 x 5 + 17
We consider the new divisor 29 and the new remainder 17,and apply the division lemma to get
29 = 17 x 1 + 12
We consider the new divisor 17 and the new remainder 12,and apply the division lemma to get
17 = 12 x 1 + 5
We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get
12 = 5 x 2 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 8143 and 7217 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(17,12) = HCF(29,17) = HCF(162,29) = HCF(191,162) = HCF(735,191) = HCF(926,735) = HCF(7217,926) = HCF(8143,7217) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 47333 > 1, we apply the division lemma to 47333 and 1, to get
47333 = 1 x 47333 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 47333 is 1
Notice that 1 = HCF(47333,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
