HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 2563, 243 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 2563, 243 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 2563, 243 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 2563, 243 is 1.
HCF(2563, 243) = 1
HCF of 2563, 243 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 2563, 243 is 1.
Highest Common Factor of 2563,243 is 1
Step 1: Since 2563 > 243, we apply the division lemma to 2563 and 243, to get
2563 = 243 x 10 + 133
Step 2: Since the reminder 243 ≠ 0, we apply division lemma to 133 and 243, to get
243 = 133 x 1 + 110
Step 3: We consider the new divisor 133 and the new remainder 110, and apply the division lemma to get
133 = 110 x 1 + 23
We consider the new divisor 110 and the new remainder 23,and apply the division lemma to get
110 = 23 x 4 + 18
We consider the new divisor 23 and the new remainder 18,and apply the division lemma to get
23 = 18 x 1 + 5
We consider the new divisor 18 and the new remainder 5,and apply the division lemma to get
18 = 5 x 3 + 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 2563 and 243 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(18,5) = HCF(23,18) = HCF(110,23) = HCF(133,110) = HCF(243,133) = HCF(2563,243) .
