HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1818, 5237 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 1818, 5237 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 1818, 5237 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 1818, 5237 is 1.
HCF(1818, 5237) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1818, 5237 is 1.
Step 1: Since 5237 > 1818, we apply the division lemma to 5237 and 1818, to get
5237 = 1818 x 2 + 1601
Step 2: Since the reminder 1818 ≠ 0, we apply division lemma to 1601 and 1818, to get
1818 = 1601 x 1 + 217
Step 3: We consider the new divisor 1601 and the new remainder 217, and apply the division lemma to get
1601 = 217 x 7 + 82
We consider the new divisor 217 and the new remainder 82,and apply the division lemma to get
217 = 82 x 2 + 53
We consider the new divisor 82 and the new remainder 53,and apply the division lemma to get
82 = 53 x 1 + 29
We consider the new divisor 53 and the new remainder 29,and apply the division lemma to get
53 = 29 x 1 + 24
We consider the new divisor 29 and the new remainder 24,and apply the division lemma to get
29 = 24 x 1 + 5
We consider the new divisor 24 and the new remainder 5,and apply the division lemma to get
24 = 5 x 4 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1818 and 5237 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(24,5) = HCF(29,24) = HCF(53,29) = HCF(82,53) = HCF(217,82) = HCF(1601,217) = HCF(1818,1601) = HCF(5237,1818) .
Here are some samples of HCF using Euclid's Algorithm calculations.
